Abstract:
A process for preparing formaldehyde di(C1- to C6-alkyl) acetals, tri(C1- to C6-alkyl) orthoformates, acetaldehyde di(C1- to C6-alkyl) acetals or tri(C1- to C6-alkyl) orthoacetatesby anodically oxidizing 1,2-di(C1- to C6-alkoxy)ethane or -propane, 1,1,2,2-tetra(C1- to C6-alkoxy)ethane or -propane, or 2,3-di-(C1- to C6-alkoxy)butane in the presence of a C1- to C6-alkyl alcohol using a customary organic compound as a cathodic depolarizer which is suitable for electrochemical reduction, and performing the anodic oxidation and the cathodic reduction in an undivided electrolysis cell in the presence of C1-C6 alkyl alcohols.
