4,4′-Diaminobenzanilide CAS no 785-30-8

Introduction of Dyestuffs And Pigments CAS 785-30-8

Iron reduction method to p-nitrobenzoic acid as raw material, chlorinated in chlorobenzene solution with thionyl chloride for chloride, nitrobenzoyl chloride chlorobenzene solution, and then in acetic acid solution with p-nitroaniline Chlorobenzene solution condensation, 4,4′-dinitroaniline Dyestuffs And Pigments CAS 785-30-8, and then reduced iron powder to give 4,4′-diamino benzanilide. After 1kg of nitro compound is reduced to 40% water to amino compound, it needs to be extracted from iron sludge by water several times, thus producing a large amount of “three wastes”. Produce 1t 4,4′-diaminobenzanilide, generate about 7t iron sludge and 70t 0.2% ammonia-containing wastewater; set special corrosion is serious, and the yield is low.
