RECOVERY OF ORGANIC ACIS FROM DILUTE SALT SOLUTIONS |
| 摘要 |
The invention includes a method for recovering an organic acid from a dilute salt solution of the acid, wherein the cation of the salt forms a carbonate salt. The method includes concentrating the solution and combining a tertiary amine, CO2, and a solvent with the solution to form a reaction product medium, an acid/amine complex and a carbonate salt. The acid/amine complex is soluble and the carbonate salt is insoluble in the reaction product medium. |

1. A method for recovering an organic acid from a dilute salt solution of the acid, wherein the cation of the salt forms a carbonate salt, comprising:
a. concentrating the solution; and b. combining a tertiary amine, CO2, and a solvent with the solution to form a reaction product medium, an acid/amine complex and a carbonate salt, wherein the acid/amine complex is soluble and the carbonate salt is insoluble in the reaction product medium. |
