A process for producing THC-O-acetate using a succession of distillation, salting-out assisted liquid-liquid extractions (SALLEs), and solvent recovery techniques. Tetrahydrocannabinol (THC) in Cannabis oil reacts with acetic anhydride with hexane and under reflux to produce THC-O-acetate and acetic acid using sulfuric acid as a catalyst. The resulting crude product is distilled and subjected to a SALLE with hexane followed by a SALLE with petroleum ether, before being distilled again in order to obtain a refined, THC-O-acetate product.
一种利用蒸馏、盐析辅助液-液萃取(
SALLE)和溶剂回收技术连续生产 THC-O-acetate 的工艺。以
硫酸为催化剂,
大麻油中的
四氢大麻酚(THC)与
乙酸酐在
正己烷和回流条件下发生反应,生成 THC-O-acetate 和
乙酸。得到的粗产品经蒸馏后与
正己烷进行
SALLE 反应,然后与石油醚进行
SALLE 反应,最后再次蒸馏以得到精制的 THC-O-acetate 产品。
