Abstract
Animal or vegetable oils or fats are first freed from fatty acids by treatment with concentrated alkali solutions in the theoretical quantity necessary or up to about 5 per cent excess, and are then decolourized &c. by alkali solution too dilute to attack the glycerides. For example, 3000 kg. of maize oil are stirred at 40 DEG C. under reduced pressure with the above proportion of 25 DEG B<\>ae. caustic soda lye, dried in vacuo, filtered or centrifuged to remove the soaps, and then agitated at about 75 DEG C. with 8 per cent of 3 DEG B<\>ae. caustic soda lye; after settling the lye is withdrawn; the oil is again washed with dilute lye, washed with water, and dried in vacuo.
