Abstract:
1. A process for preparing alkoxylated alkyl (ether) amines of formula (I) with peaked distribution using a catalyst with a multiple-charge counterion, wherein said process comprises reacting, in a first step, a primary alkylamine (II) with an alkylene oxide in order to yield the first intermediate (III) followed by reacting, in a second step, the intermediate (III) with (m) additional moles of alkylene oxide in the presence of a catalyst with multiple-charge counterions to yield the desired final alkoxylated alkyl (ether) amine product (I) wherein R is selected from a linear or branched, saturated or non-saturated alkyl group containing 8-22 carbon atoms, or is a group of the formula: wherein A, B, X, Y, are alkylene oxide groups containing 2-4 carbon atoms, C is an alkylene group containing 3-4 carbon atoms, a, b each vary from 0-5, c is 1, x is 1, y varies from 1- 15, n moles of alkylene oxide is from 1 to 2, and m moles of alkylene oxide is from 1-18.
