Abstract
Inventia se refera la un procedeu de obtinere a N-triclormetiltetrahidroftalimidei prin reactia de condensare a perclormetilmecarcaptanului cu sarea de sodiu a tetrahidroftalimidei în mediu apos în raport molar de 1: 1.....1: 1,3 si la temperaturi cuprinse între 0 si 10 degree constînd din aceea ca sarea de sodiu a tetrahidroftalimidei se adauga sub agitare energeticaîn decurs de 5....60 min, de preferinta 5....10 min, la o suspensie apoasa de perclormetilmercaptan continînd 1% emulgator si 0,5....60% sulf muiabil, dupa care produsul tehnic obtinut se stabilizeaza prin spalare cu suspensie fina de carbonat de calciu, dupa spalare prealabila cu apa.
