【摘要】 考察了在以邻氨基苯甲酸为原料 ,三氯化铁为催化剂 ,X为溶剂 ,直接通氯氯化 ,再经重氮化合成3,5 -二氯苯甲酸的工艺过程中 ,物料配比、反应温度等反应条件对收率的影响 ,确定了合成的适宜条件。通过此合成工艺 ,产品的收率可达 85 %以上。更多还原

【Abstract】 dichloro benzoic acid is synthesized with o -amino benzoic acid as the raw material and ferric chloride as the catalyst and solvent X,by dinect passing chlorine and diazotization.Reaction conditions such as ratio of raw materials,reaction temperature and so on to the effect of yields are discussed.Using this process,the yield may be up to over 85%.更多还原
