Abstract

PURPOSE: To separate the titled compound, easily, in high efficiency, from the suspension obtained by the thermal dehydration reaction of an alkanolamine with sulfuric acid or alkanolamine acidic sulfate in a suspending medium, by removing the produced water, and then adding an aqueous solution of alkali hydroxide to the suspension.
CONSTITUTION: An alkanolamine, e.g. the compound of formuoa [R is -R'''CH- (R''' is H or lower alkyl) or phenylene; R' and R" are H or lower alkyl; n is 1W3], and sulfuric acid or alkanolamine acidic sulfate are heated and dehydrated in a suspending medium (e.g. benzene), and the produced water is removed by azeotropic distillation. 10W35Wt% aqueous solution of an alkali hydroxide is added to the reaction products to dissolve the suspending aminoalkanol sulfuric acid ester in the solution. The aqueous solution of alkali hydroxide containing the sulfuric acid ester as a solute is separated from the reaction system to obtain the aminoalkanol sulfuric acid ester from the suspending medium.
