| titleOfInvention | Process for the preparation of sodium-ethanolamine salts of monoester of sulfosuccinic acid and polyoxyethyl alcohols or polyoxyethylalkylphenols |
| abstract | 1. Method for the preparation of sodium-ethanolamine salts of sulfosuccinic acid monoesternand polyoxyethyl alcohols or polyoxyethylalkylphenols by sulfonation reactionnacid monoester of maleic acid and polyoxyethyl alcohol, or polyoxyethylalkylphenol,ncharacterized in that the monoester sulfonation process is carried out in an aqueous solutionnsodium hydrogen sulphite and ethanolamine, at elevated temperature, possibly atnthe presence of a mixture of inorganic salts such as sodium sulfate and sodium chloride. |
