    摘要： An alkoxylation catalyst is prepared by a) reaction of one mol of a dicarboxylic acid with from 1.5 to 8 mol of an alkoxylated alcohol to form the corresponding dicarboxylic monoester, b) formation of an alkaline earth metal salt of the dicarboxylic monoester by addition of water and from 0.45 to 0.55 mol of a basic alkaline earth metal compound per mol of dicarboxylic acid originally used, c) partial neutralization of the alkaline earth metal salt by addition of from 0.25 to 0.7 mol of H2SO4 per mol of basic alkaline earth metal compound originally used and d) removal of the water present at a temperature of less than 100° C. The catalyst prepared in this way makes it possible to prepare colorless alkoxylates having a narrow homologue distribution.
