Tosylhydrazine Use and Manufacturing

Methods of Manufacturing

P-toluenesulfonyl chloride and hydrazine hydrate are condensed in benzene medium at 60-70°C, and the discharged hydrogen chloride is absorbed with water. Filter, wash with water, and dry at 65°C to obtain the foaming agent TSH. The benzene layer in the filtrate is used for recycling, and the water layer can recover hydrazine sulfate. Raw material consumption (kg/t) p-toluenesulfonyl chloride (96.8%) 1110 hydrazine hydrate (40%) 820 benzene 520
