Abstract
Inventia se refera la un procedeu pentru prepararea 1,1-dimetilhidrazinei, prin reactia cloraminei cu dimetilamina în mediu apos, în care se prepara o solutie de cloramina, prin reactia unei solutii 12....13% de clorura de amoniu la pH 8...9 cu o solutie de hipoclorit de sodiu 12%, la o temperatura cuprinsa între -5 si +5 degree C, care se adauga la solutia de dimetilamina care contine NaOH, în asa fel încît raportul molar hipoclorit de sodiu/clorura de amoniu si dimetilamina este de 1 : 1,2 : 4, la temperatura de 34 degree C obtinîndu-se dimetilhidrazina în solutia diluata, care se toarna peste solutia NaOH la un raport 22...24/1 parti în greutate, uar dupa terminarea degazarii se distileaza 1,1-dimetilhidrazina.
