Abstract

Preparation of 3-alkoxy- or 3,3-dialkoxycarboxylic acid esters of the formula <IMAGE> in which R denotes hydrogen, optionally substituted alkyl, optionally substituted aryl or optionally substituted heteroaryl, R' and R" each denote hydrogen or OR"', with it not, however, being possible for R' and R" both to be hydrogen, and R"' denotes optionally substituted alkyl, by conducting keten gas, while stirring and controlling the temperature, into a suspension of an acid silicate catalyst, such as an acid clay mineral or a zeolite, in an acetal or orthoester of the formula <IMAGE> which is, where appropriate, dissolved in a suitable solvent, and, after the reaction has come to an end, removing the catalyst and working up the reaction mixture, thereby obtaining a high degree of conversion of the keten which has been conducted in, and a high yield.
