1.
3,6-epoxy-1,2,3,6-tetrahydrophthalic anhydride was prepared by reacting maleic anhydride with furan in anhydrous ether,which was subsequently acting as the endcapping agent for the synthesis of a series of polyimide oligomers with different chain length.
由顺丁烯二酸酐和呋喃在无水乙醚中反应得到3,6-环氧-1,2,3,6-四氢邻苯二甲酸酐,以此作为封端剂合成链节数为1,2,3的聚酰亚胺低聚物。

补充资料：环丁烷
分子式C4H8，分子量56.10，无色气体，燃烧时有火焰。熔点为-80℃，沸点11℃。液化点-15℃。不溶于水，溶于乙醇、丙酮。用作纤维素醚溶剂。环丁烷的制备可由环丁烯在加热并用镍作催化剂氢化制得，也可用环丁烷羧酸脱羧制得，或者用1.4-二溴丁烷与金属锌在醇溶液中进行反应而制得。
