Qualified color developing agent CD 4, 3 methyl 4 amino N ethyl N(β hydroxyethyl) aniline sulfate, is synthesized by hydroxyethylation, nitrosation, reduction and salt forming using 3 methyl aniline as raw material. The total product yield can reach over 60%. 以N乙基间苯甲胺为主要原料,通过羟乙基化、亚硝化、还原和成盐等步骤得到性能合格的成品,合成彩色显影剂CD4,总收率达到60%以上。
Controlled current oscillographic potentiometric titration of very weak bases ( NaAc, aniline, hexamethylenetetramine, pyridine) in concentrated salt solutions with hydrochloric acid was studied. 本文研究了浓盐溶液中极弱碱(NaAc、苯胺、六次甲基四胺、吡啶)的控制电流示波电位滴定。
In this experiment, we used o-methyl aniline as raw material reacting with n-BuLi, and got o-toluidine lithium salt. 本实验以邻甲基苯胺为原料,先与正丁基锂反应,得到邻甲基苯胺锂盐。
