Preparation of hydroxyl group-containing alkoxylation products of organic carboxylic acids |
| abstract |
The present invention relates to a process for the preparation of alkoxylation products of organic carboxylic acids containing alcoholic hydroxyl groups by the reaction of any organic compounds containing at least one carboxyl group with alkylene oxides in an alkoxylation reaction in the presence of catalysts, characterized in that the catalysts used are phase transfer catalysts selected from the group consisting of (a) tetraalkylammonium or tetraalkylphosphonium halides in which the sum of carbon atoms of the alkyl groups is at least 8, (b) basic alkali metal compounds converted into complexes with crown ethers and (c) complexes of (i) basic alkali metal compounds and (ii) acyclic organic compounds containing at least 5 alkylene oxide units of the formula -R-O- (R=C1-C4-alkylene) in the form of one or more polyether chains having at least 3 alkylene oxide units, said compounds having a molecular weight of at least 238 and containing a total of at least 40% by weight of alkylene oxide units of the type indicated in polyether chains having at least 3 alkylene oxide units. The present invention also relates to the use of these alkoxylation products for the production of polyurethanes by reaction with organic polyisocyanates. |
