9.The liquid phase oxidation of p -toluic acid at 190 ℃ in the presence of manganese acetate,cobalt actate and tetrabromoethane was studied.
研究了以醋酸、醋酸锰和四溴乙烷为催剂,在190℃时,对甲基苯甲酸液相氧制对苯二甲酸的过程。
10.and the prolonged resident time helps removel of Sb,hawever,this will cause the redissolution of cobalt into the solution.
升高温度对除、锑有利;延长反应时间对除锑有利,而出现返溶。
11.This paper has studied the phthalocyanin complex of Cobalt synthesized by benzene bitter wine-urea law,and after depuration,an infrared, ultra-violet spectrograph determination is carried.
