Abstract:
1. An alkoxylated alkyl (ether)amine composition with peaked distribution comprising a mixture of homologs of the formula: 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: where A, B, X, Y, Z are alkylene oxide groups containing 2-3 carbon atoms, R′ is selected from a linear or branched, saturated or non-saturated alkyl group containing 8-22 carbon atoms, C is an alkylene group containing 2-4 carbon atoms, a, b each vary from 0-5, c is 1, x is 1, y, y′, z and z′ each independently vary from 1-15; wherein said mixture of homologs of said alkoxylated alkyl(ether)amine composition with peaked distribution is characterized by a degree of peaking that is at least 5% higher than that of the conventional non-peaked alkoxylated alkyl(ether)amines having the same carbon-chain length and average EO chain length prepared via conventional base catalysis, wherein conventional base catalysis comprises NaOH-catalyzed reaction of RNH 2 with alkylene oxide conducted entirely under autogenous pressure up to 90 psig (621 kPa) at a catalyst concentration of 0.2 wt. % and a temperature between 160° and 180° C., and wherein said alkoxylated alkyl(ether)amine contains less than 5% by weight (poly)ethylene glycol derivatives based on the weight of said alkoxylated alkylamine and/or alkoxylated alkyletheramine composition.
