Title: Manufacture of pure saturated fatty acids and their esters
IPC: C11C3/12
Filed: 1947-01-24
Abstract: Pure fatty acids such as stearic acid and esters thereof are prepared by dehydrating a saturated hydroxy acid or ester such as hardened castor oil to give an unsaturated acid or ester, hydrogenating the unsaturated product, and, if desired, esterifying or splitting the acid or ester.  In an example, hardened castor oil is heated in presence of a small amount of phosphoric acid for 30 minutes at 280 DEG  C. in a stream of nitrogen. The dehydrated ester is then hydrogenated at 200 DEG  C. and 100 lb. per sq. in. pressure in the presence of nickel catalyst and split to give a mixture of stearic and iso-oleic acids.  Crystallisation from acetone yields pure stearic acid.  In another example, the dehydrated oil is saponified, split, and the fatty acids esterified with methanol.  The methyl esters are distilled and hydrogenated, yielding substantially pure methyl stearate from which stearic acid may be obtained.  In a third example, the dehydrated oil is reacted with excess of ethylene glycol at 100-200 DEG  C. and refluxed with methanol in the presence of sodium. A mixture of 85 per cent methyl iso-oleate and 15 per cent methyl stearate is obtained which is vacuum distilled and then hydrogenated to give substantially pure methyl stearate.  Starting materials referred to other than castor oil are ivory wood oil and Cephalocroton Cordofanus seed oil.ALSO:Pure fatty acids such as stearic acid and esters thereof are prepared by dehydrating a saturated hydroxy acid or ester such as hardened castor oil to give an unsaturated acid or ester, hydrogenating the unsaturated product and, if desired, esterifying or splitting the acid or ester.
