Abstract
Abstract IN WHICH R1, R2 and R3 are alkyl radicals having 1-3 carbon atoms, and X is an anionic group as halogen, sulfate, phosphate, characterized by the addition of usual organic solvents, and of alkaline alkyl sulfosuccinates or alkylsulfosuccinamates. Concentrated and stable salts of epoxypropyltrialkyl ammonium which are less sensitive to the action of atmospheric humidity, which salt crystallizes pure, and corresponding to the formula:
