METHOD FOR PRODUCING ORTHOCARBONIC ACID TRIALKYL ESTERS

A process is provided for the preparation of trialkyl orthocarboxylates by the electrochemical oxidation of alpha, beta-diketones or alpha, beta-hydroxyketones, the keto group being present in the form of a ketal group derived from C1- to C4-alkylalcohols and the hydroxyl group optionally being pres...

Zusammenfassung:	A process is provided for the preparation of trialkyl orthocarboxylates by the electrochemical oxidation of alpha, beta-diketones or alpha, beta-hydroxyketones, the keto group being present in the form of a ketal group derived from C1- to C4-alkylalcohols and the hydroxyl group optionally being present in the form of an ether group derived from C1- to C4-alkylalcohols (ketals K), in the presence of C1- to C4-alcohols (alcohols A), the molar ratio of the ketals K to the alcohols A in the electrolyte being 0.2:1 to 10:1.
