METHOD FOR PRODUCING ORTHOCARBONIC ACID TRIALKYL ESTERS

The invention relates to a method for producing orthocarbonic acid trialkyl esters by electrochemical oxidation of alpha-beta-diketones or alpha-beta-hydroxy ketones in the presence of C1-to C4-alcohols (alcohol A), the keto function being present in the form of a ketal function derived from C1- to...

Zusammenfassung:	The invention relates to a method for producing orthocarbonic acid trialkyl esters by electrochemical oxidation of alpha-beta-diketones or alpha-beta-hydroxy ketones in the presence of C1-to C4-alcohols (alcohol A), the keto function being present in the form of a ketal function derived from C1- to C4-alykl alcohols and the hydroxyl function being optionally in the form of an ether function derived from C1- to C4-alykl alcohols (ketal K). The molar ratio of the ketal K to the alcohols A in the electrolytes is 0.2:1 to 10:1.
