MANUFACTURING METHOD OF PURIFIED URUSHIOL AND PURIFIED URUSHIOL MANUFACTURED BY THE SAME

摘要

The present invention relates to a method of manufacturing purified urushiol and purified urushiol manufactured thereby, and more particularly, to a method of manufacturing purified urushiol, including mixing crude lacquer with xylene, centrifuging the mixture, adding ammonia water and formalin, and conducting condensation and then purification at high temperatures, and to purified urushiol manufactured using the same.
