Abstract: |
|||
| A process for preparing a monoester disodium sulfosuccinate whose chemical formula is R(CH2CH2O)nCOCH2CH(SO3Na)COONa, where R is dismutated abietic acid, esterified abietic acid, hydrogenated abietic acid, dismutated abietylamine, esterified abietylamine, dismutated abietylamide, esterified abietylamide, or the adduct of esterified rosin-acrylic acid includes ethoxylation, esterification and addition reactions. Said compound series is a multi-effect anionic surfactant used as disperser of calcium soap, emulsifier and penetrant. | |||
