Several works have been reported of the concentration of oleyl oleate from sperm oil. But the oleate oleyl concentrated from sperm oil is so unstable due to the presence of highly unsaturated components that the application of oleyl oleate is limited. It is therefore, necessary to reduce these highly unsaturated components in the oleyl oleate concentrate. <BR>The authors attempted to decrease the amounts of polyunsaturated components in sperm body oil by two procedures. The one was to thermally polymerize sperm oil in the presence of active earth, and the other was to hydrogenate the oil selectively with Cu-Cr catalyst under atmospheric pressure. The oleyl oleate was concentrated from thus treated sperm body oils and untreated oil through molecular distillation and fractional crystallization. A.O.M. stabilities of these oleyl oleate concentrates were determined according to the A.O.C.S. analytical method. The oleyl oleate concentrate obtained from thermally polymerized sperm body oil was most stable, while the oleyl oleate from untreated sperm oil was unstable most.
