PROBLEMS OF THE PRODUCTION OF MODIFIED FATS

Abstract

The article provides an overview of the catalysts used to obtain modified fats. The main types of contacts are analyzed: the efficiency of dispersed copper-nickel catalysts promoted by palladium, platinum, and chromium is studied; supported copper-nickel catalysts and alloy catalysts are studied. The influence of such factors as composition, preparation methods, methods of modification on their activity, selectivity, and isomerizing ability is considered. The types of promoters and their classification are presented. It is shown that for the hydrogenation of vegetable. in particular. of cottonseed oils, alloyed nickel-aluminum catalysts with various additives are the most promising. The use of palladium, molybdenum, and rhodium as promoters in the hydrogenation of cottonseed oil and miscella improves the catalytic properties of these contacts.
