Literature Abstracts

During the war the Fischer-Tropsch process was developed as the starting point for numerous processes yielding chemicals rather than fuels. Besides giving a detailed description of the synthesis-gas manufacture and the catalyst chambers used in the normal and medium-pressure processes, this report deals with: (1) The manufacture and recovery of the Co catalyst; and (2) the chemical and economic aspects of the Oxo process in which C₁₂-C₁₅ alcohols are formed by hydrogenation of aldehydes produced by the reaction of olefins and synthesis gas over a Co catalyst. Reaction (2) also was studied in relation to a wide variety of other compounds, for example, cyclic olefins, styrene, butadiene, oleic alcohol, rubber, and vinyl ether. Costs are quoted as pf. 77 per kg. of alcohol. Much information was obtained on the manufacture of synthetic lubricating oils, the oxidation and chlorination of waxes, and the direct synthesis of higher alcohols and fatty acids.
