Abstract
Procedeul de obtinere a unor alchileteriglicoli, conform inventiei, se caracterizeaza prin aceea ca, în scopul cresterii randamentului de obtinere a unor fractiuni distincte de metiletermonopropilenglicol metileterdipropolenglicol, metileterpolipropilenglicol cu proprietati spumante, utilizate în flotatia minereurilor se trateaza alcolul metilic cu oxidul de propilena în raport molar de 1 : 3.....1 : 4,5 în doua trepte de temperatura cuprinse în intervalele 100....160 degree C, 160....180 degree C, presiunea fiind de 8....10 at si se supune distilarii sub vid de 10 mm Hg si la temperatura de 115 degree C, produsul de reactie separat de metiletermono so dipropilenglicoli.
