Abstract: Necessity of crude lanolin refinement was expressed simplely, and the processing method and the new development of lanolin refinement both at home and abroad are introduced. By using a quadplex–component refining agent, through acidification, refining, settlement, crocking, washing and dehydration, high-quality lanolin will be produced. Comparing to the traditional method of refining wool fat ,using this method, the purity of lanolin is higher, the cost is lower and the operation is more convenient .The waste product of this method can be used to produce diatomic lanolin salt which can be used in rust-proof and lubrication, therefore, the problem of polluting is resolved. Through the experiment, the result enunciate that the most suitable and proper reaction conditions is that: the proportion of quadplex–component (Na5P3O10: Na2SO4: NaOH: H2O) is 6:6:3:85, the temperature of refining is 90℃ ,the choice of settlement solvent is Isopropanol, at 60 ℃ under six hours with hydrogen peroxide decolorization. Through the refining process to yield to lanolin can reach 85% and the colour is better.
