Abstract

Inventia de fata se refera la un procedeu de preparare a unor fenilcarbamati substituiti activi erbicid, de formula generala I (vezi formula în pag.1 a descrierii) care se prepara prin reactionarea N-hidroxifenilcarbamatilor respectivi, fie ca izocianati de formula generala R indice 1 -N=C=O sau cloruri de aminoacizi R indice 1 -NH-COCl, în mediu apos, evitînd astfel folosirea de solventi organici. Produsul final poate fi extras dintr-o suspensie apoasa într-un solvent nemiscibil cu apa. N-hidroxifenilcarbamatii se pot prepara prin reactionarea 3-aminofenolului cu cloroformati în mediu apos, si produsul rezultat poate fi reactionat in situ, fara izolare, cu izocianati în acelasi vas de reactie.
