Abstract
Procedeu pentru prepararea, unui amestec de N-hidroxietil si N,N-dihidroxietil-p-aminobenzoati de alchil cu 1...4 atomi de carbon, caracterizat prin aceea ca, în scopul maririi sigurantei în exploatare, esterul alchilic al acidului p-aminobenzoic se trateaza cu etilenclorhidrina în exces, în prezenta unui agent bazic de legare a acidului clorhidric ales dintre hidroxid, oxid sau carbonat de metal alcalin, folosind excesul de etilenclorhidrina ca solvent, la temperaturi cuprinse între 80 si 160 degree C.
