Title:
SOLVENT FOR EXTRACTION AND SOLVENT EXTRACTION PROCESS
Document Type and Number:
Japanese Patent JP2003040818
Kind Code:
A
Abstract:

To provide a solvent for extraction excellent in chemical stability, having solvent power similar or superior to the conventional solvents for extraction such as halogenated aliphatic hydrocarbons or esters, having a proper boiling point, free from dangers of inhaling vapors of the solvent in solvent extraction process, easy to remove the solvent by vaporization, reducing problems of the environmental contamination, and to provide a solvent extraction method of an organic compound using the same.

This solvent for extraction comprises at least a kind of trifluoromethylbenzene compound expressed by general formula (1) (R is F or a trifluoromethyl group, n is 0, 1 or 2). And the solvent extraction method comprises extraction of the organic compound from a solid or liquid mixture including the organic solvent, has a process contacting the mixture with the solvent for extraction and then separating the solution of the solvent for extraction including the organic solvent.
