二亚苄基山梨醇的合成

The Synthetic of Dibenzylidene Sorbitol (DBS)

本文采用改进的方法合成了二亚苄基山梨醇（ＤＢＳ），收率在９５％以上， 并将ＤＢＳ加入到聚丙烯中，验证了ＤＢＳ能够增大成核密度，使聚丙烯透明性增加。

The article is used of improving synthetic mothed to synthesize DBS, the productivity achieve above 95%. When BBS are put into PP, it validate that DBS can increase the density of nucleation, and it can increase clarity of PP.
