Abstract

Polyalkanolamines are obtained by passing an olefine oxide containing not more than five carbon atoms into contact with an anhydrous alkanolamine of formula R-NH-R1, in which R is a monohydroxy alkyl radical and R1 is hydrogen or a monohydroxy alkyl radical, neither of which contains more than five carbon atoms, in the absence of a solvent and of ammonia, at a temperature maintained between 0 DEG and 100 DEG C., the oxide being added in a molecular proportion, relative to the alkanolamine, not exceeding 1:1 when R1 is a monohydroxy alkyl radical and not exceeding 2:1 when R1 is hydrogen. Suitable oxides are ethylene oxide, propylene oxide, isobutylene oxide and butadiene monoxide. Suitable alkanolamines as starting materials, are monoethanolamine, monoisopropanolamine, monoisobutanolamine, diethanolamine, diisopropanolamine and monoethanol monoisopropanolamine. Preferably the reaction is conducted under reflux or in a closed vessel at a pressure at least equal to the autogenous pressure of the reaction mixture. In the examples (a) monoethanolamine is reacted with ethylene oxide to give a mixture of triethanolamine and diethanolamine; (b) propylene oxide is reacted with monoisopropanolamine to give triisopropanolamine with a little di-isopropanolamine; and (c) propylene oxide is reacted with diethanolamine to give diethanolmonoisopropanolamine. U.S.A. Specification 2,373,199 is referred to.
