  • Unsymmetrical sulfosuccinate diesters
    Patent number: 4480119
    Abstract: Unsymmetrical sulfosuccinate diesters in which one carboxyl group of the sulfosuccinate is esterified with an alcohol, for instance, a C.sub.8 -C.sub.12 aliphatic monohydric alcohol such as octyl or dodecyl alcohol, or with an ethoxylated or propoxylated alkyl phenol, and in which the other carboxyl group is esterified by reaction with ethylene oxide, and method of preparation of such diesters. The said diesters have utility as surfactants, such as detergents and emulsifiers.
    Type: Grant
    Filed: June 18, 1979
    Date of Patent: October 30, 1984
    Inventors: Kermit D. Longley, Anastasios J. Karalis
  • Sulfosuccinate diesters
    Patent number: 4310683
    Abstract: Sulfosuccinate diesters in which one carboxyl group of the sulfosuccinate is esterified with an ethoxylated or propoxylated non-tertiary monoamine, for instance, a C.sub.8 -C.sub.18 fatty amine, ethoxylated with 3 or 4 moles of ethylene oxide, to form a hydroxyl-containing tertiary amine, and in which the other carboxyl group of the sulfosuccinate is esterified with an .alpha.-monoepoxide such as propylene oxide, or higher .alpha.-monoepoxides, and method of preparation of such sulfosuccinate diesters. The said sulfosuccinate diesters have utility as surfactants, such as detergents and emulsifiers.
    Type: Grant
    Filed: June 15, 1979
    Date of Patent: January 12, 1982
    Assignee: Witco Chemical Corporation
    Inventors: Kermit D. Longley, Anastasios J. Karalis
  • Sulfosuccinate ester-amides
    Patent number: 4154955
    Abstract: Sulfosuccinate ester-amides in which one carboxyl group of the sulfosuccinate is amidified with an aliphatic non-tertiary amine, for instance, a C.sub.8 -C.sub.12 aliphatic amine such as octyl or dodecyl amine, and in which the other carboxyl group of the sulfosuccinate is esterified by reaction with an .alpha.-monoepoxide such as propylene oxide, or higher .alpha.-monoepoxides, and method of preparation of such sulfosuccinate ester-amides. The said sulfosuccinate ester-amides have utility as surfactants, such as detergents and emulsifiers.
