Abstract
257,170. Eisenstein, A. Feb. 16, 1926. Purifying fats and fatty oils; obtaining fatty acids by decomposing fats and fatty oils.-Fatty acids are removed from glycerides by the addition of a soap insoluble in the glycerides. The fatty acids are adsorbed by the soap, which is then removed from the glycerides, as by means of a salt solution of lower specific gravity than the soap. The separated acids contain no neutral oil. An acid oil may be neutralized by this means by adding soap thereto, or by partly saponifying the acids present and using the soap thus formed to remove the remaining acids, or by completely saponifying the acids in a portion of the oil and using the oil-bearing soap so obtained to remove the acids in a second portion of the oil, the oil in the soap then being replaced by acids. In the last event, the soap containing fatty acids may have the last traces of oil removed by centrifuging, pressing, or blowing with air &c. The method of separation can also be used for obtaining fat-free fatty acids from the products obtained by decomposing fats and oils by the autoclave or reactive processes, the decomposition being prematurely interrupted and the reaction mixture being then treated with soda lye and a salt solution, the fatty acids obtained on adding hydrochloric acid being free from neutral fat. Examples are given of the removal of acids from olive oil and palm oil, and from train oil by a series of processes, and of the production of pure fatty acids from lard.
