Abstract: An improved process for making ethoxylated amine compounds such as ethanolamines. The improvement comprises the addition of an acid to the amine compound prior to the addition of ethylene oxide to a reactor wherein the ethoxylated amine compound is prepared. The improvement reduces the concentration of undesirable glycol ether and/or vinyl ether ethoxylate byproducts which may contribute to undesirable properties, such as color and foaming, of the ethoxylated amine compounds.
Abstract translation: 一种制备乙氧基化胺化合物如乙醇胺的改进方法。 改进之处在于向环氧乙烷加入其中制备乙氧基化胺化合物的反应器中的胺化合物中加入酸。 该改进降低了不希望的乙二醇醚和/或乙烯基醚乙氧基化物副产物的浓度，这可能有助于乙氧基化胺化合物的不合需要的性质，如着色和发泡。
