Abstract
Inventia se refera la un procedeu de obtinere a esterilor acidului stearic cu monoetilenglicol, propilenglicol sau dietilenglicol si consta în aceea ca, în scopul simplificarii procesului se esterifca stearina cu monoetilenglicol, propilenglicol saudietilenglicol într-o singura faza în topitura, în prezenta oxidului de zinc catalizator, într-un raport molar stearina: diol: catalizator, cu eliminarea apei prin distilare pe coloana cu umplutura, la presiune atmosferica 3-4 h, apoi prin distilareîn vid progresiv pîna la o presiune remanenta de 10...20mbar, cu îndepartarea excesului de diol prin distilare în vid.
