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.
一种改进的制备乙氧基胺化合物(如
乙醇胺)的方法。该改进包括在将乙氧化物添加到反应器中制备乙氧基胺化合物之前,向胺化合物中添加酸。该改进减少了不良的
乙二醇醚和/或
乙烯醚乙氧基化合物副产物的浓度,这些副产物可能导致乙氧基胺化合物的颜色和起泡等不良性能。
