Catalysts for esterification of epoxidized soyates and methods of using same
Abstract:
A combination of catalysts is disclosed as useful to promote the transesterification reaction of an epoxidized soyate with a polyol to yield a high percentage of epoxidized soyate diester with epoxy functionality retained. The primary catalyst is a metallic hydroxide, and the secondary catalyst is a titanate. Bioderived plasticizers useful for thermoplastics and thermosets result.
Abstract(Chinese):

公开了催化剂的组合可用于促进环氧化大豆油与多元醇的酯交换反应，以产生高百分比的具有环氧官能团保留的环氧化大豆油二酯。 主催化剂是金属氢氧化物，二次催化剂是钛酸盐。 生物活性增塑剂可用于热塑性塑料和热固性材料。
