摘要:
A process for producing unsaturated fatty compounds having improved low-temperature properties bya) splitting lauric oils into fatty acids and glycerol,b) subjecting the fatty acids to fractional crystallization to obtain a fraction of unsaturated fatty acids, andc) hydrogenating the unsaturated fatty acids, optionally after converting the unsaturated fatty acids into their lower alkyl esters, to form unsaturated fatty alcohols having an iodine value of from about 85 to about 100.
摘要:
Fatty mixtures containing fatty alcohols having 16 to 24 carbon atoms, wax esters and fatty ketones are solid at temperatures of up to 65.degree. C. and are particularly useful as mold release agents in the building, rubber and plastics-processing industries.
