    b. 11 October 1884 Goldschmieden, near Breslau, Germany
    d. 31 March Buenos Aires, Argentina

    After studying chemistry in Breslau and Leipzig and assisting inter alia at the institute of Fritz Haber in Karlsruhe on the catalysis of ammonia under high pressure, in 1909 he went to Hannover to pursue his idea of turning coal into liquid hydrocarbon under high hydrogen pressure (200 atm) and high temperatures (470° C). As experiments with high pressure in chemical processes were still in their initial stages and the Technical University could not support him sufficiently, he set up a private laboratory to develop the methods and to construct the equipment himself. Four years later, in 1913, his process for producing liquid or organic compounds from coal was patented.
    The economic aspects of this process were apparent as the demand for fuels and lubricants increased more rapidly than the production of oil, and Bergius's process became even more important after the outbreak of the First World War. The Th. Goldschmidt company of Essen contracted him and tried large-scale production near Mannheim in 1914, but production failed because of the lack of capital and experience to operate with high pressure on an industrial level. Both capital and experience were provided jointly by the BASF company, which produced ammonia at Merseburg, and IG Farben, which took over the Bergius process in 1925, the same year that the synthesis of hydrocarbon had been developed by Fischer-Tropsch. Two years later, at the Leuna works, almost 100,000 tonnes of oil were produced from coal; during the following years, several more hydrogenation plants were to follow, especially in the eastern parts of Germany as well as in the Ruhr area, while the government guaranteed the costs. The Bergius process was extremely important for the supply of fuels to Germany during the Second World War, with the monthly production rate in 1943–4 being more than 700,000 tonnes. However, the plants were mostly destroyed at. the end of the war and were later dismantled.
    As a consequence of this success Bergius, who had gained an international reputation, went abroad to work as a consultant to several foreign governments. Experiments aiming to reduce the costs of production are still continued in some countries. By 1925, after he had solved all the principles of his process, he had turned to the production of dextrose by hydrolyzing wood with highly concentrated hydrochloric acid.

    SUBJECT AREA: Chemical technology
    [br]
    b. 7 March 1839 Cassel, Germany
    d. 11 December 1909 London, England
    [br]
    German (naturalized English) industrial chemist.
    [br]
    Born into a prosperous Jewish merchant family, Mond studied at the Polytechnic in Cassel and then under the distinguished chemists Hermann Kolbe at Marburg and Bunsen at Heidelberg from 1856. In 1859 he began work as an industrial chemist in various works in Germany and Holland. At this time, Mond was pursuing his method for recovering sulphur from the alkali wastes in the Leblanc soda-making process. Mond came to England in 1862 and five years later settled permanently, in partnership with John Hutchinson \& Co. at Widnes, to perfect his process, although complete success eluded him. He became a naturalized British subject in 1880.
    In 1872 Mond became acquainted with Ernest Solvay, the Belgian chemist who developed the ammonia-soda process which finally supplanted the Leblanc process. Mond negotiated the English patent rights and set up the first ammoniasoda plant in England at Winnington in Cheshire, in partnership with John Brunner. After overcoming many difficulties by incessant hard work, the process became a financial success and in 1881 Brunner, Mond \& Co. was formed, for a time the largest alkali works in the world. In 1926 the company merged with others to form Imperial Chemical Industries Ltd (ICI). The firm was one of the first to adopt the eight-hour day and to provide model dwellings and playing fields for its employees.
    From 1879 Mond took up the production of ammonia and this led to the Mond producer-gas plant, patented in 1883. The process consisted of passing air and steam over coal and coke at a carefully regulated temperature. Ammonia was generated and, at the same time, so was a cheap and useful producer gas. Mond's major discovery followed the observation in 1889 that carbon monoxide could combine with nickel in its ore at around 60°C to form a gaseous compound, nickel carbonyl. This, on heating to a higher temperature, would then decompose to give pure nickel. Mond followed up this unusual way of producing and purifying a metal and by 1892 had succeeded in setting up a pilot plant to perfect a large-scale process and went on to form the Mond Nickel Company.
    Apart from being a successful industrialist, Mond was prominent in scientific circles and played a leading role in the setting up of the Society of Chemical Industry in 1881. The success of his operations earned him great wealth, much of which he donated for learned and charitable purposes. He formed a notable collection of pictures which he bequeathed to the National Gallery.

  • 6 Macintosh, Charles

    [br]
    b. 29 December 1766 Glasgow, Scotland
    d. 25 July 1843 Dunchattan, near Glasgow, Scotland
    [br]
    Scottish inventor of rubberized waterproof clothing.
    [br]
    As the son of the well-known and inventive dyer George Macintosh, Charles had an early interest in chemistry. At the age of 19 he gave up his work as a clerk with a Glasgow merchant to manufacture sal ammoniac (ammonium chloride) and developed new processes in dyeing. In 1797 he started the first Scottish alum works, finding the alum in waste shale from coal mines. His first works was at Hurlet, Renfrewshire, and was followed later by others. He then formed a partnership with Charles Tennant, the proprietor of a chemical works at St Rollox, near Glasgow, and sold "lime bleaching liquor" made with chlorine and milk of lime from their bleach works at Darnley. A year later the use of dry lime to make bleaching powder, a process worked out by Macintosh, was patented. Macintosh remained associated with Tennant's St Rollox chemical works until 1814. During this time, in 1809, he had set up a yeast factory, but it failed because of opposition from the London brewers.
    There was a steady demand for the ammonia that gas works produced, but the tar was often looked upon as an inconvenient waste product. Macintosh bought all the ammonia and tar that the Glasgow works produced, using the ammonia in his establishment to produce cudbear, a dyestuff extracted from various lichens. Cudbear could be used with appropriate mordants to make shades from pink to blue. The tar could be distilled to produce naphtha, which was used as a flare. Macintosh also became interested in ironmaking. In 1825 he took out a patent for converting malleable iron into steel by taking it to white heat in a current of gas with a carbon content, such as coal gas. However, the process was not commercially successful because of the difficulty keeping the furnace gas-tight. In 1828 he assisted J.B. Neilson in bringing hot blast into use in blast furnaces; Neilson assigned Macintosh a share in the patent, which was of dubious benefit as it involved him in the tortuous litigation that surrounded the patent until 1843.
    In June 1823, as a result of experiments into the possible uses of naphtha obtained as a by-product of the distillation of coal tar, Macintosh patented his process for waterproofing fabric. This comprised dissolving rubber in naphtha and applying the solution to two pieces of cloth which were afterwards pressed together to form an impermeable compound fabric. After an experimental period in Glasgow, Macintosh commenced manufacture in Manchester, where he formed a partnership with H.H.Birley, B.Kirk and R.W.Barton. Birley was a cotton spinner and weaver and was looking for ways to extend the output of his cloth. He was amongst the first to light his mills with gas, so he shared a common interest with Macintosh.
    New buildings were erected for the production of waterproof cloth in 1824–5, but there were considerable teething troubles with the process, particularly in the spreading of the rubber solution onto the cloth. Peter Ewart helped to install the machinery, including a steam engine supplied by Boulton \& Watt, and the naphtha was supplied from Macintosh's works in Glasgow. It seems that the process was still giving difficulties when Thomas Hancock, the foremost rubber technologist of that time, became involved in 1830 and was made a partner in 1834. By 1836 the waterproof coat was being called a "mackintosh" [sic] and was gaining such popularity that the Manchester business was expanded with additional premises. Macintosh's business was gradually enlarged to include many other kinds of indiarubber products, such as rubber shoes and cushions.

  • 10 Artificial Cotton

    This is prepared from the barked trunks of pine trees by the reduction of thin shavings into wood-wool, which is washed, then acted upon by steam, and heated with caustic soda under pressure, being thus converted into cellulose. This paste-like substance is reheated and pressed through a form of sieve into threads. By treating with ammonia and sprinkling with water these threads are made flexible and as easy to work as cotton. The wood is not abundant, and the cost of production is very heavy, which tends to prevent this fibre becoming a commercial success. In 1933, a Japanese company claimed that they could produce this material so cheaply that it would compete successfully with cotton.

    SUBJECT AREA: Chemical technology
    [br]
    b. 31 March 1811 Göttingen, Germany
    d. 16 August 1899 Heidelberg, Germany
    [br]
    German chemist, pioneer of chemical spectroscopy.
    [br]
    Bunsen's father was Librarian and Professor of Linguistics at Göttingen University and Bunsen himself studied chemistry there. Obtaining his doctorate at the age of only 19, he travelled widely, meeting some of the leading chemists of the day and visiting many engineering works. On his return he held various academic posts, finally as Professor of Chemistry at Heidelberg in 1852, a post he held until his retirement in 1889.
    During 1837–41 Bunsen studied a series of compounds shown to contain the cacodyl (CH3)2As-group or radical. The elucidation of the structure of these compounds gave support to the radical theory in organic chemistry and earned him fame, but it also cost him the sight of an eye and other ill effects resulting from these dangerous and evil-smelling substances. With the chemist Gustav Robert Kirchhoff (1824–87), Bunsen pioneered the use of spectroscopy in chemical analysis from 1859, and with its aid he discovered the elements caesium and rubidium. He developed the Bunsen cell, a zinc-carbon primary cell, with which he isolated a number of alkali and other metals by electrodeposition from solution or electrolysis of fused chlorides.
    Bunsen's main work was in chemical analysis, in the course of which he devised some important laboratory equipment, such as a filter pump. The celebrated Bunsen gas burner was probably devised by his technician Peter Desdega. During 1838–44 Bunsen applied his methods of gas analysis to the study of the gases produced by blast furnaces for the production of cast iron. He demonstrated that no less than 80 per cent of the heat was lost during smelting, and that valuable gaseous by-products, such as ammonia, were also lost. Lyon Playfair in England was working along similar lines, and in 1848 the two men issued a paper, "On the gases evolved from iron furnaces", to draw attention to these drawbacks.

    b. 1834 Ghent, Belgium d. 1882
    [br]
    Belgian chemist, photographic researcher, inventor and author.
    [br]
    Born in Belgium of German stock, Monckhoven spoke German and French with equal fluency. He originally studied chemistry, but devoted the greater part of his working life to photography. His improved solar enlarger of 1864 was seen by his contemporaries as one of the significant innovations of the day. In 1867 he moved to Vienna, where he became involved in portrait photography, but returned to Ghent in 1870. In 1871 he announced his discovery of a practicable collodion dry-plate process, and later in the decade he conducted research into the carbon printing process. In 1879 Monckhoven constructed a comprehensively equipped laboratory where he commenced a series of experiments on gelatine dry-plate emulsions, including some which yielded the discovery that the ripening of silver bromide was greatly accelerated by ammonia; this allowed the production of emulsions of much greater sensitivity. He was a prolific author, and his 1852 book on photography, Traité général de photographie, published when he was only 18, became one of the standard texts of his day.
