used as complexing agent, basic gas dehydrating agent, dye intermediate, solvent for resin and rubber accelerator
production method the production method is dichloroethane amination. 1, 2-dichloroethane and aqueous ammonia were fed to a tubular reactor for hot-pressing amination at a temperature of 150 ° C. To 250 ° C. And a pressure of 392.3kPa. The reaction solution was neutralized with alkali to obtain a mixed free amine, which was concentrated while removing sodium chloride. Then, the crude product was distilled under reduced pressure to cut off a fraction between 195 and 215 ° C. To obtain a finished product. This method can simultaneously produce ethylenediamine, diethylenetriamine, tetraethylenepentamine and polyethylenepolyamine, which can be obtained by controlling the temperature of the distillation column to distill the amine mixture and cutting off different fractions for separation.
spontaneous combustion temperature 335°C
