METHOD FOR PRODUCING DIALKYL DICARBONATES

摘要

The invention relates to a novel method for producing dialkyl dicarbonates by reacting the corresponding halogenated formic acid alkyl esters with alkali or alkaline earth hydroxides and/or carbonates in the presence of water-immiscible organic solvents and in the presence of a catalyst. The invention is characterized in that at least one tertiary alkyl amine of the formula (I), wherein the substituents are defined as in the description, is used as the catalyst. ® KIPO & WIPO 2007
