摘要
用小分子混合醇降解废聚酯碎片。考察了小分子多元醇、催化剂对反应产物的影响。该方法主要工艺参数如下:n(PET):n(PG)=1:2~3,醋酸锌质量分数为0.1%,醇解温度180—190℃。醇解时间6h。
The waste PET scraps was degradated with low molecular mixed polyalcohol. The effects of the low molecular polyalcohol and catalyst on reaction product were studied. The main process parameters of the method are as follows:the ratio of n(PET) to n(PE) is 1: 2 -3 ,the mass fraction of zine acetate is 0. 1% ,the alcoholysis temperature is 180 - 190℃ ,the alcoholysis time is 6 h.
