PURIFICATION METHOD OF URUSHIOL AND PURIFIED URUSHIOL OBTAINED THE ABOVE METHOD

摘要

After mixing the raw lacquer with the organic solvent, purifying the urushiol by filtration by a multi-stage filter, and separating the urushiol and the organic solvent by fractional distillation, if necessary, improving not only the yield of urushiol but also continuous, economical and mass production. The present invention relates to an easy method for purifying urushiol and a purified urushiol obtained therefrom, wherein (1) a raw lacquer harvested from lacquer trees is selected from the group consisting of xylene, ethanol, benzene, toluene, acetone or a mixture of two or more thereof. Dissolving in, but the dissolving step of mixing and dissolving the raw lacquer: organic solvent in a ratio of weight ratio of 1: 1 to 2 times by weight ratio; And (2) a filtration step of filtering the lacquer solution dissolved in the organic solvent in a multistage filter composed of 2 to 10 filters having meshes of different specifications.
