Triethylenediamine Use and Manufacturing

Methods of Manufacturing

1, 2-Dichloroethane and ammonia water are fed into the tubular reactor, and are heated and autoclaved at 150-250°C under a pressure of 392 kPa. The reaction solution is neutralized with alkali to obtain mixed free amine, concentrated to remove sodium chloride, then the crude Lv is distilled under reduced pressure, and different fractions are collected for separation. At the same time of obtaining the product, it also produces ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine and polyethylenepolyamine in parallel. This product can be obtained by fractional distillation from the mother liquor producing piperazine hexahydrate, and the first production of 100t piperazine hexahydrate can obtain about 3-4t of triethylenediamine hexahydrate.

Uses
