diazo-salt 重氮盐
Poly (N-vinyl carbazole) was modified to prepare azo-PVK by post-azo-coupling reaction with diazo salt as raw material using phase-transfer catalysts.
我们以聚乙烯咔唑为偶合组分,和发色基团对硝基苯重氮盐在相转移催化剂存在下,采用后重氮偶合方法,制备出偶氮化聚乙烯咔唑。
The molar mass proportion of PVK and diazo salt is 1:4. Diazo salt was divided into several parts and added into solution in batches at room temperature to react for 96 hours.
聚乙烯咔唑和重氮盐摩尔质量比1:4,重氮盐按分批加入方式加入到反应液中,反应时间96小时,反应温度室温。
