cyclic anhydride meaning in Chinese

环酸酐
环酐

When a conjugated system was contained in the cyclic anhydride , it gave n - phenylimide as the major product
结果表明，环酐的分子结构直接影响反应结果，当酸酐分子存在共轭结构时以n -芳基内酰胺为主要产物。
The amidation and esterification of different cyclic anhydrides with aniline and phenol gave different major products , and the routes were optimized
摘要研究了环酐与苯胺和苯酚的酰胺化及酯化反应，优化了酰胺化及酯化反应条件。
