A method of manufacture and purification lanolin cholesterol using for Liquid crystal is studied. We analyzed the effect of the proportion of materials and ethanol,ethanol concentration,amount of alkali added and the reaction temperature on lanolin saponification rate,the effect of selection and amount of solvent crystallization on the product quality,and the effect of pH of alkali washing and acid washing on the product purity,then determined various factors and the optimal process conditions affecting the manufacture and purification of lanolin cholesterol. By using the process, the content of lanolin cholesterol can be up to 99.0%. The content and various impurities can reached standard requirements for lanolin cholesterol using for liquid crystal.
