467. DE BARTHOLOMAEIS, E., AND DE NORA, V. Process for Reducing Organic Compounds by Hydrogenation. United States Patent 2,597,074, May 20, 1952; appl. filed May 22, 1948, Serial No. 28,604; 11 claims (Cl. 260-638). Chem. Abs., vol. 47, 1953, p. 2199.

Describes improved operating method for producing higher molecular alcohols and the other hydrogenating products by the reaction of H₂ or gases containing H₂ with fatty or other organic materials under high pressures and temperatures in presence of a catalyst. The process is applicable to the reduction of Fischer-Tropsch fatty acids or esters to alcohols. With this improved process, it is possible to operate continuously instead of by batch hydrogenation and also to permit a more rapid and uniform reaction. This advantage has been accomplished by maintaining the reaction autoclave always under operating conditions of H₂ pressure and temperature and by charging the raw material and discharging the products without changing appreciably the pressure of temperature in the autoclave. Provision also is made for continuously circulating H₂ through the reaction autoclave during the hydrogenation process. This step not only stirs and mixes the substances involved in the reaction but also permits elimination of H₂O and also reduction products volatile at the temperature of the autoclave.
