Methods for the isolation of cholesterol from wool alcohols are discussed and a process is described which is based on the formation of a cholesterol-oxalic acid complex by reaction of the wool alcohols with anhydrous oxalic acid in ethyl acetate or benzene. The sparingly soluble complex is isolated and converted to pure cholesterol or cholesteryl acetate as desired.
