Preparation of N,N'-dichloro-terephthalamide or N,N'-dichloro-isophthalamide by chlorination of an aqueous suspension of the corresponding terephthalamide or isophthalamide under acid conditions in which the dilution of the reaction mixture is sufficient to maintain the hydrogen chloride being produced as a by-product of the chlorination substantially completely dissolved in the reaction mixture up to the end of the reaction. The compound N,N'-dichloro-terephthalamide has been discovered to be a very stable mild oxidizing agent useful as an antiseptic. Both compounds obtained by the disclosed preparation are valuable intermediate compounds.
通过在相应的苯二甲酰胺或异苯二甲酰胺的水悬浊液中在酸性条件下氯化制备N,N'-二氯苯二甲酰胺或N,N'-二氯异苯二甲酰胺,其中反应混合物的稀释足以保持氯化产生的氢氯酸作为副产物在反应结束时在反应混合物中基本完全溶解。发现N,N'-二氯苯二甲酰胺是一种非常稳定的温和氧化剂,可用作防腐剂。通过所述制备得到的两种化合物是有价值的中间体化合物。
