Definitions
- the present invention relates to a process for the preparation of formaldehyde di (C 1 to C 6 alkyl) acetals, ortho-formic acid tri- (C 1 to C 6 alkyl) esters, acetaldehyde di ( C 1 - to C 6 -alkyl) - acetals or ortho-acetic tri- (C 1 - to C 6 -alkyl) esters (compounds 1) by anodic oxidation of 1,2-di- (C 1 - to C 6 - alkoxy) ethane or propane, 1,1,2,2-tetra (C 1 to C 6 alkoxy) ethane or propane, or 2,3-di- (C 1 to C 6 alkoxy) -butane (compounds II) in the presence of a C 1 - to C 6 -alkyl alcohol (compounds III) in which the cathodic depolarizer used is a customary organic compound (compounds IV) which is suitable for electrochemical reduction and in
- compounds II are 1,2-di (C 1 - to C 6 alkoxy) ethane or propane or 1,1,2,2-tetra (C 1 - to C 6 alkoxy) ethane or -propane used.
- compounds I the corresponding formaldehyde di (C 1 - to C 6 alkyl) acetals or ortho-antric acid tri (C 1 - to C 6 alkyl) esters are formed and, in the case of the propane derivatives as starting materials also acetaldehyde di- (C 1 - to C 6 alkyl) - acetals or Orthoessigklatri- (C 1 - to C 6 alkyl) ester.
