Abstract
311,665. Kernot, J., C. Dec. 10, 1927, Fats and fatty oils, purifying.-Fish oils are deacidified and bleached by acting thereon below 100‹ C. with aqueous caustic alkali solution, separating the aqueous layer, washing the oil, agitating it with concentrated aqueous sulphur dioxide or like sulphurous bleaching agent, separating the oil, repeating the bleaching treatment if necessary, and again washing. In an example, 0.5 ton of dog-fish oil is stirred into 112 lb. of a 5 per cent solution of caustic soda previously heated to 90‹ C. The emulsion is allowed to stand for 24 hours, when the lower aqueous layer is run off. The upper layer is washed with hot water, treated with an equal volume of a saturated solution of sulphur dioxide, washed with hot water, and dried and filtered with fullers' earth, animal charcoal, or other suitable decoloriser. Further bleaching may be effected by hydrogenating below 200‹ C. preferably in presence of a catalyst consisting of a mixture of the hydrated oxides of nickel and aluminium.
