The invention provides a method for separating wool oil and wool wax in wool fat, which is characterized in that according to different molecular sizes of wool oil and wool wax in crude wool fat, separation of wool wax and wool oil in a clarified wool fat solution is realized by adopting a nanofiltration membrane with specific molecular weight cutoff. Compared with the traditional solvent fractional crystallization method, the method has the advantages of high raw material recycling rate, thorough separation of the wool oil and the wool wax, high quality of the obtained wool oil and wool wax, and high separation speed. Compared with a molecular distillation method, the method disclosed by the invention has the advantages that the defects that chemical components are damaged by high temperature, burnt taste is generated and the color is deep are avoided; and the whole process has no phase change process, is low in energy consumption, is green and environment-friendly, and is easy for industrial production. 本发明
