Application

在制备聚-ε-己内酯（PCL）-羟基磷灰石（HA）支架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）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

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。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。在THF的合成过程中丁-1,4-二醇作为中间体而被形成。热的THF可用于聚偏二氯乙烯（PVDV）的溶解。
