studies on Acetalization of Litsea Cubeba Oil with Glycol Catalyzed by Dealuminated USY

In this paper, the acetalization of litsea cubeba oil and glycol by using dealuminated USY zeolite as catalyst was studied. The change of the main components in litsea cubeba oil before and after the acetalization , the reaction rate of two isomers in litsea cubeba oil and repeated use of the catalyst were investiguted. The experimental results showed that dealuminated USY was a good catalyst, and the acetalization could be finished in 4 hours with over 94% yield under the appropriate reaction conditions. This method was convenient and feasible for industrial production.
