Abstract
559,076. Soap manufacture. SHARPLES CORPORATION. April 22, 1942, No. 5413. Convention date, April 23, 1941. [Class 91] Soap, preferably for re-cycling to succeeding soap-making batches, is separated from the nigre by purifying the latter by a treatment comprising adding thereto a source of acid so as to reduce in quantity or completely neutralize the free alkali of the nigre, and thereafter removing insoluble impurities from the treated nigre, such as by centrifuging. A source of acid signifies a free acid or an ester capable of furnishing an acid radical for combination with the free alkali of the nigre. The treated nigre is sufficiently heated to effect the neutralization. Soap-making fatty acids or the original fats are preferably used such as cocoanut, tallow, cottonseed, corn, palm kernel, and soya bean oils and rosin or the free fatty acids. The neutralizing treatment enhances the separation of the insoluble impurities which can then be removed. Other acids or esters may be used for the treatment, such as aliphatic and aromatic sulphonic acids, and hydrochloric acid. The acid-treated nigre may be diluted with water.
