产品描述

General description

四氢呋喃(THF)被广泛用作溶剂。它构成了各种天然产物(聚醚抗生素)的关键片段。[1]THF可与硫化氢形成双水合物。该双水合物的晶体结构已通过三维单晶体研究而被探究。[2]在THF的合成过程中丁-1,4-二醇作为中间体而被形成。[5]热的THF可用于聚偏二氯乙烯(PVDV)的溶解。[6]

Application

在制备聚-ε-己内酯(PCL)-羟基磷灰石(HA)支架[3]和丙烯酸酯封端的聚(5-氨基-1-戊醇 - 共-1,4-丁二醇二丙烯酸酯)(C32)-1,3-二氨基戊烷(117)聚合物)[4]过程中,四氢呋喃可分别用于溶解聚-ε-己内酯(PCL)和1,3-二氨基戊烷。

适用于HPLC、分光光度法、环境检测
