| titleOfInvention | Process For Continuously Preparing Dialkyl Carbonate |
| abstract | The present invention comprises purifying a dialkyl carbonate of formula (II) in one or more columns in the presence of an alkylene oxide of formula (V) and an alkyl alcohol of formula (IV), wherein the dialkyl carbonate Wherein the average residence time is from 0.3 h to 3 h: ≪ (IV) (V) Wherein R 1 and R 2 are, independently of each other, a linear or branched, substituted or unsubstituted C 1 -C 6 -alkyl; R 3 and R 4 independently of one another are hydrogen, substituted or unsubstituted C 1 -C 4 -alkyl, substituted or unsubstituted C 2 -C 4 -alkenyl, or substituted or unsubstituted C 6 -C 12 - represents aryl; R 5 represents straight-chain or branched C 1 -C 4 -alkyl. |
