摘要
在ＥＧ的沸点下，ＰＥＴ在ＥＧ中的醇解速度较慢．若在醇解体系中添加适量ＢＨＥＴ，由于ＢＨＥＴ与ＰＥＴ良好的相容性，会加速醇解反应；若再同时添加Ｚｎ（ＯＡｃ）２等催化剂，会进一步加速醇解反应；若在醇解体系中ＥＧ，适量ＢＨＥＴ，Ｚｎ（ＯＡｃ）２及微量Ｈ２Ｏ同时并存，则会获得最佳醇解效果．这一研究不仅具有理论意义，也可供聚酯类生产厂家借鉴．
The alcoholysis speed of polyethylene terephthalate (PET) in ethylene glycol (EG) will be greatly accelerated when definite amount of bis-hydroxyethyl terephthalate (BHET) is added because of the good compatibility between PET and BHET.The optimal alcoholysis results can be obtained when BHET, Zn(OAc)2 and a little H,O are added together into the alcoholysis system.
