A novel monomer the 1-methyl-4,5-bis(4-chlorobenzoy) cyclometer containing cyclohexene were prepared,so a group of novel polys containing the cyclohexene and phthalazinone moieties was prepared by the nucleophilic displacement reaction of 1-methyl-4,5-bis(4-chlorobenzoyl) cyclohexene and 4,4′-dichlorodiphenyl sulfone and 4-(3,5-dimethyl-4-hydroxyphenyl)-2,3-phthalazin-1-one.

用新型聚合单体1-甲基-4，5-二(4-氯代苯甲酰基)环己烯与4-(4-羟基苯基)-2，3-二氮杂萘-1-酮、4，4′-二氯二苯砜单体经亲核共缩聚反应，成功地合成了含环己烯结构的杂环联苯型聚醚系列聚合物。

The synergistic extraction of uranyl nitrate with binary system of 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5 and tributyl phosphate or diphenyl sulfoxide, and ternary system of PMBP-DPSO-TBP were studied.

本文研究了1-苯基3-甲基4-苯甲酰吡唑酮-5与磷酸三丁酯或二苯亚砜的苯溶液从硝酸介质中对U的萃取，实验发现有显著的二元协萃效应，并测定了二元协萃络合物的组成为 UO_2A_2·TBP或 UO_2A_2·DPSO，求得二元协萃平衡常数为1gβ_(12)=3.58，1gβ_(13)=3.61。

In our work, as a preliminary experiment, the N-phenacylisoquinolinium bromide was reacted with methlhydrazine in refluxed acetic acid. Unexpectedly, 2-methyl-1,2,3-triazole was obtained. The further study of this reaction led to a more simple starting material,α-bromoacetophenone to react with methylhydrazine, obtaining the same product.

我们在研究N-苯乙酰异喹啉溴化物与甲肼在冰醋酸中的反应时，意外地得到了2-甲基-4-苯基-1，2，3-三氮唑，经过进一步的研究发现α-溴代苯乙酮与甲肼也能得到同样的产物。
