| titleOfInvention | Process for preparing and/or purifying amido acid phenyl ester sulfonates |
| abstract | The present invention relates to a process for the preparation of a purified salt of 4-sulfophenyl-[(1-oxyalkanoyl)amino]alkanoate. The process comprises the steps of: (a) providing a source of 4-sulfophenyl-[(1-oxyalkanoyl)amino]alkanoate; (b) admixing the source with a water-based purification system to form a purification mixture, the water-based purification system having water present at a ratio of 4-sulfophenyl-[(1-oxyalkanoyl)amino]alkanoate to water ranging from about 1:0.05 to about 1:50, preferably from about 1:0.1 to about 1:40; (c) separating a purified salt of 4-sulfophenyl-[(1-oxyalkanoyl)amino]alkanoate from the purification mixture; and (d) collecting said purified salt of 4-sulfophenyl-[(1-oxyalkanoyl)amino]alkanoate. In preferred embodiments, the purification mixture includes a processin aide such as ethyl alcohol, propyl alcohol, isopropyl alcohol, acetone and mixtures thereof. |
