Precursor for alkoxylation catalysts |
摘要 |
A precursor for alkoxylation catalysts is prepared by reacting a chelating anionic or nonionic phase transfer catalyst with an alkaline earth metal compound in the presence of a compound which can be alkoxylated. Suitable phase transfer catalysts are, in particular, ethoxylated fatty alcohols, ether carboxylic acids, ether sulfonic acids or ether phosphonic acids. Addition of sulfuric acid to such a precursor produces an alkaline earth metal sulfato complex which is the actual catalyst for the alkoxylation.
