Title:
SEPARATION OF LANOLIN FATTY ACIDS
Document Type and Number:
Japanese Patent JP3359056
Kind Code:
B2
Abstract:
PURPOSE: To provide a separation process for easily producing an ω- hydroxyfatty acid methyl ester, a non-hydroxyfatty acid methyl ester and an α-hydroxyfatty acid methyl ester having faint color in almost odorless state on an industrial scale in high efficiency.
CONSTITUTION: This process for the separation of lanolin fatty acids comprises the separation and purification of an ω-hydroxyfatty acid methyl ester from a lanolin fatty acid methyl ester by solvent fractionation. Another embodiment of the invention is a process for the efficient separation and purification of a non-hydroxyfatty acid methyl ester and an α-hydroxyfatty acid methyl ester by the low-temperature column treatment of a lanolin fatty acid methyl ester left after separating and removing an ω-hydroxyfatty acid methyl ester.
