    摘要: The invention relates to a process for preparing tertiary ether amines corresponding to the following general formula: ##STR1## by reacting in the presence of a strong base a tertiary amine corresponding to the following formula: ##STR2## with a sulfuric acid semi-ester salt corresponding to the following formula:R.sup.1 --(OC.sub.n H.sub.2n).sub.x --OSO.sub.3 M. (III)Preferably, each mole of the tertiary amine corresponding to formula (II) is reacted under substantially anhydrous conditions at a temperature of 140.degree. to 230.degree. C. with from about 0.2 to 3.0 moles of the sulfuric acid semi-ester salt of formula (III) in the presence of from about 1 to 1.5 moles of a strong base preferably an alkali metal hydroxide or an alkali metal alcoholate.
