METHOD AND DEVICE FOR CARBOXYLIC ACID PRODUCTION

摘要

A multi-compartment electrolysis cell includes an anodic compartment, a cathodic compartment, and a solid alkali ion transporting membrane (such as a NaSICON membrane). An anolyte is added to the anodic compartment. The anolyte comprises an alkali salt of a carboxylic acid, a first solvent, and a second solvent. The alkali salt of the carboxylic acid is partitioned into the first solvent. The anolyte is then electrolyzed to produce a carboxylic acid, wherein the produced carboxylic acid is partitioned into the second solvent. The second solvent may then be separated from the first solvent and the produced carboxylic acid may be recovered from the second solvent. The first solvent may be water and the second solvent may be an organic solvent.

1. A device for producing carboxylic acid comprising:
a multi-compartment electrolysis cell comprising an anodic compartment, a cathodic compartment, and a solid alkali ion transporting membrane; an anode in communication with the anodic compartment; a cathode in communication with the cathodic compartment; a power source in communication with the anode and the cathode for creating a current therebetween; and an anolyte comprising an alkali salt of a carboxylic acid, a first solvent and a second solvent, wherein the alkali salt of the carboxylic acid is partitioned into the first solvent, wherein a carboxylic acid produced in the cell is partitioned into the second solvent.
