摘要： The invention provides a process for purifying raw lanolins containing agricultural chemicals by removing the residual agricultural chemicals therefrom, which comprises subjecting the raw lanolins to at least one of the step (1) of hydrogenation in a molten state or in an organic solvent in the presence of a hydrogenation catalyst at a temperature of 60 to 210°C under a hydrogen pressure of 1 atm or more with a hydrogen consumption of 0.001 to 0.05 wt. % based on the raw lanolin, the step (2) of distillation in vacuo at a temperature of 150 to 280°C under an absolute pressure of 10 to 500 x 10-3 mmHg, and the step (3) of adsorption on a resin selected from among those containing styrene-divinylbenzene as a skeleton, those containing acrylic ester as a skeleton and polystyrene resins and having a micropore size of about 10 to 250 Å or on a crystalline aluminosilicate having an internal diameter of about 9 to 13 Å.
