HOE 75/F 009 k PROCESS FOR PREPARING N-(.alpha.-ALKOXYETHYL)-CARBOXYLIC ACID AMIDES Abstract of the disclosure: N-.alpha.-alkoxyethyl carboxylic compounds of the formula Image wherein R5 means hydrogen, an alkyl group having from 1 to 6 carbon atoms or an aryl group having from 6 to 10 carbon atoms, especially hydrogen or the CH3 group, and wherein R6 means an alkyl group having from 1 to 6 carbon atoms, especially the CH3 group, are prepared by electrolysis of secondary N-ethylcarboxylic acid amides of the formula Image with alcohols of the formula R6OH, R5 and R6 having the aforesaid meaning, while employing tetraalkyl ammonium tetra- fluoroborates, tetraalkyl ammonium hexafluorophosphates as well as alkali-tetrafluoroborates as conducting salts and a current quantity of at least 2.5 Faraday/mole of N-ethylcarboxy- lic acid amide. The N-.alpha.-alkylethyl compounds are valuable intermediate products for the preparation of N-vinyl carboxylic acid amides which may then be converted to water-soluble poly- mers having multiple properties for technical application.
