Abstract
Inventia se refera la un procedeu pentru obtinerea esterilor stearici ai polietilenglicolilor cu mase moleculare între 200-4000, constînd în aceea ca se supun esterificarii într-o singura faza, polietilenglicoli cu acid stearic tehnic, în conditii stoechiometrice, în atmosfera inerta, cu catalizator oxid de zinc, la presiunea atmosferica iar în final sub vid, apa de reactie fiind distilata pe o coloana cu umplutura, ameliorarea culorii se realizeaza prin adaugarea de acid hipofosforic.
