Abstract
2202. Sandberg, G. Jan. 29. Fats and fatty oils; fatty acids; candles; soaps.- Relates to the manufacture of an odourless consistent product from seal, whale, dolphin, or like oils, suitable for use in the manufacture of soap or candles. The fatty acids obtained by saponifying the fats in any known way are treated with sulphuric acid, commencing at a temperature of 12‹-20‹ C. and concluding at a temperature of 25‹-40‹C. The mass is washed and the sulpho acids decomposed by treatment with steam. The process may be modified by allowing the final temperature of the acid treatment to reach 60‹-70‹ C., when the congealing temperature of the product will be higher. The anhydrides present are converted into fatty acids by treatment of the mass in autoclaves with water under steam pressure. A mixture of nitrous and sulphuric acids may be used in place of sulphuric acid.
