Embodiment 1
[0030] (1) Get 200g of crude lanolin, obtain 172g of anhydrous lanolin by refining processes such as decolorization and acid value reduction, and detect that the Gardner chroma is 7.2, the acid value is 0.63mgKOH / g, and the pesticide residue value is 65.2ppm (pesticide residue The value is detected by gel chromatography separation GPC-solid phase extraction SPE-gas chromatography detection GC method). (USP43, EP10 lanolin detection method)
[0031] (2) Turn on the vacuum system of molecular distillation, adjust the number of molecular booster pumps in high vacuum equipment, and adjust the vacuum degree. The vacuum degree of the first-level molecular distillation is stable at 12Pa, and the vacuum degree of the second-level molecular distillation is displayed as 0.1Pa; adjust the first-level molecular distillation The distillation temperature is 120°C, the distillation temperature of the secondary molecular distillation is 160°C, and the temperature of the condensing system is 5...
