(I) We studied the degree of concentration of liver oils by furfural under various conditions, and the results obtained were as follows.<br> (a) The good concentrating ratio is obtained at from 20°C. to 30°C., and the good yield is obtained at 60°C..<br> (b) The volume of solvent about 3 times of liver oil is a proper quantity to get the good results.<br> (c) Under the same volume of solvent, the repeated extraction showes the best result.<br> (d) The result of higher iodine value oil is better than that of lower oil.<br> (II) Aniline proved of use for concentrating vitamin oils, as it was proposed a new solvent.
