Process for extracting sulfonic acids |
| abstract |
SULFONIC ACIDS IN THE PRODUCT FROM A SULFOXIDATION REACTION ARE SEPARATED FROM SULFURIC ACID BY EXTRACTING WITH AT LEAST ONE ORGANIC SOLVENT THE HEAVY PHASE RESULTING FROM THE PROCESS REACTION. SUITABLE ORGANIC SOLVENTS INCLUDE HALOGENATED COMPOUNDS SUCH AS CARBON TETRACHLORIDE, CHLOROBENZENE AND ETHYLENE DICHLORIDE. FROM 400 TO 600% BY VOLUME OF SOLVENT IS USED, AND ROOM TEMNERATURE IS PREFERRED. |
