process for preparing dialkylcarbonates |
| abstract |
PROCESS FOR PREPARING DIALKYL DICARBONATES The new process for preparing dialkyl dicarbonates by reacting the corresponding halic formic acid alkyl esters with alkaline or alkaline earth hydroxides and / or carbonates in the presence of non-miscible organic solvents in the presence of a catalyst is characterized in that at least one tertiary alkylamine of formula (I) NR 1 R 2 R 3 (I) is employed as catalyst, wherein the substituents have the meaning given in the description. |
