摘要：NOVELTY - Preparation of 4,6-diaminoresorcinolhydrochloride comprises dispersing 4,6-dinitro-2-chloro-1,3-dihydroxybenzene into aqueous solution, adding dechlorination accelerator in presence of rare metal catalyst, reacting with hydrogen for 0.5-2 hours, carrying out salinification to obtain 4,6-diaminoresorcinolhydrochloride. The catalyst comprises carrier and rare metal loaded on the carrier. The carrier is steady for reacted aqueous solution. The dechlorination accelerator is ammonium acetate, ammonium formate and/or sodium formate. USE - Method for preparing 4,6-diaminoresorcinol hydrochloride (claimed). ADVANTAGE - The method provides 4,6-diaminoresorcinolhydrochloride with high yield and high quality by using economic mode. The method is environmental-friendly because it provides reaction wastewater that can be easily be treated and provides wide industrialization production prospect.
