什么是1,4-二-2,5-酮CAS502-97-6?

1,4-dioxacyclo-2,5-hexadione是一个循环酯产生的脱水的两种分子的乙醇酸,这是用来准备聚乙醇酸(联盟)的单体。

重50乙醇酸并把它放到500毫升的双口瓶中,然后添加0.05克苯丙氨酸stinious催化剂(0.1重%),prepolymerize为0.5h在大气压和120℃,然后使温度升高到160℃,真空脱水通过真空蒸馏设备、反应约2h,直至无水被排出,白聚物可以获得。

然后,1,4-dioxacyclo-2,5-hexadione收集decompressure裂至260℃,并33.9克的1,4-dioxacyclo-2,5-hexadione后获得5h。 产品收率是89%,和在熔点的产物90.6℃以上。
