酞菁蓝B合成方法改进

Improvement of the Synthetic Method for Pigment Copper Phthalocyanine

以苯酐、尿素、氯化亚铜为反应物合成颜料酞菁蓝 B,用硝基苯代替工业常用的三氯苯作溶剂 ,通过改变溶剂、氯化亚铜的用量和反应时间 ,优化反应条件 ,酞菁蓝 B的收率达到 93% ,纯度为 95% .

Use phthalic anhydride,Urea and Cu 2Cl 2 as reactor.With solvent phNO 2,instead of usual C 6H 3Cl 3,it gives more copper phthalocyanine by changing volume of solvment,weight of Cu 2Cl 2 and time of reaction than before.
