摘 要: | 本文采用沉淀滴定法测定环氧树脂氯含量,用邻苯二甲酸二甲酯代替剧毒的硝基苯作为AgCl沉淀的保护剂。同时,把AgNO_3标准溶液和NH_4CN标准溶液配得较稀,使得对含氯量极微的环氧树脂中氯值的分析更为准确。

DETERMINATION OF CHLORINE CONTENT OF EPOXY RESIN |
| |
Abstract: | The chlorine content of epoxy resin was determined with a preciptation titration method, with dimethyl o-phthalate used as protecting agent for AgCl precipitate instead of toxic nitrobenzene. To obtain more precise values for the epoxy resin containing trace of chlorine , the standard AgNO3 solution and NH4CH solution should be made thinner. |
