Process for the preparation of surfaceactive derivatives of 5 - sulfoisophthalic acid |
| abstract |
SURFACE-ACTIVE ESTER AND AMIDE SALTS OF 5-SULFOISOPHTHALIC ACID ARE PREPARED BY REACTING AN ALKALI OR ALKALINE EARTH METAL SALT OF 5-SULFOISOPHTHALIC ACID DIMETHYL ESTER WITH AN ALCOHOL OR AN AMINE HAVING 4 TO 12 CARBON ATOMS IN THE ALKYL GROUP TO PRODUCE THE DESIRED DIALKYL ESTER AND DIALKYL AMIDE SALTS, RESPECTIVELY, OF 5-SULFOISOPHTHALIC ACID. |
