Environmental-friendly liquid fuel and production process thereof

摘要

The present invention discloses a liquid fuel and production process thereof, the liquid fuel comprises dialkyl carbonates with the structural formula of;
wherein R and R′ are same or different, and R and R′ are selected from the group consisting of C1-C8 linear chain alkyl, C3-C8 branched chain alkyl, C3-C8 naphthene base and alkyl containing furan ring. The process of the production of the liquid fuel comprises the steps of: performing a cycloaddition reaction between 2-methyl tetrahydrofuran produced by hydrogenation from furfural which is a biomass derivative and carbon dioxide to produce a cyclic carbonate (i.e. 1,4-pentanediol carbonate), then performing an ester exchange reaction between the cyclic carbonate and monohydric alcohol to produce the dialkyl carbonate. The liquid fuel produced is clean, safe and biodegradable, and the process provides a new way for industrial production of the dialkyl carbonate with remarkable economic and social benefit.

1. A process for the production of liquid fuel, wherein the process comprises performing an ester exchange reaction between a cyclic carbonate and a monohydric alcohol selected from one or more of the group consisting of C1-C8 linear chain alcohol, C3-C8 branched chain alcohol, C3-C8 cyclic alcohol and alcohol containing furan ring,
wherein the cyclic carbonate is 1,4-pentanediol carbonate, and wherein the process further comprises performing a cycloaddition reaction between 2-methyl tetrahydrofuran and carbon dioxide to produce the 1,4-pentanediol carbonate.
