出　　处：《Journal of Chemistry and Chemical Engineering》2012年第3期263-267,共5页化学与化工（英文版）

摘　　要：The process of production of lactide from butyl lactate was investigated. The process consists of two stages： oligomerisation of butyl lactatean and depolymerisation of oligomers. The type catalysts of the series of Lewis acid were tested. It was found that SnCI4 is the most efficient catalyst for both stages.
