HIGH PRESSURE AND HEAT
IMPORTANT INDUSTRIAL DEVELOPMENTS
(From Our Own Correspondent.) (Bt Air Mail) LONDON, June 1
The use of high pressure, in addition to heat, in bringing about chemical action has become of great industrial importance, and the report of the Chemistry Research Board for 1934 indicates what lines of research have been recently pursued. The method for obtaining nitrogen fertilisers from the air and the conversion of coal and tar into motor spirit are two pioccsses which are being developed. Pioneer work on high pressure chemistry has been carried out for some time at the laboratory. Alcohols, including the important ethyl alcohol, have been produced there by direct interaction of carbon monoxide and hydrogen under pressure. In addition, acetic acid, a substance of great industrial importance in many industries —-for example, the artificial silk industry —has been obtained by the interaction of ethyl alcohol and carbon monoxide. The equipment has recently been constructed for work at 3000 times atmospheric pressure at a temperature of 200 deg C. The development of high-pressure chemistry is still in its early stages, but it is noteworthy that the starting point of the syntheses referred to are materials obtainable from coal.
