  • Fuel compositions containing esters and ester-type dispersants
    Patent number: 4032303
    Abstract: Improved fuel compositions with decreased tendency to form deposits in the carburetor and on "early fuel evaporation" heating elements, inlet valves and the like contain a normally liquid fuel (usually a hydrocarbon fuel), a carboxylic acid ester which is either (1) an ester of a polyol and a C.sub.5 -C.sub.15 monocarboxylic acid or (2) an alkanol ester of a substituted succinic acid, and an oil-soluble, ester-type, nitrogen-free dispersant derived from a polyhydric alcohol and characterized by the presence therein of a substantially saturated aliphatic hydrocarbon-based radical having at least about 30 carbon atoms.
    Type: Grant
    Filed: October 1, 1975
    Date of Patent: June 28, 1977
    Assignee: The Lubrizol Corporation
    Inventors: Casper John Dorer, Jr., Clark Ober Miller
  • Fuel compositions containing esters and nitrogen-containing dispersants
    Patent number: 4032304
    Abstract: Improved fuel compositions with decreased tendency to form deposits in the carburetor and on "early fuel evaporation" heating elements, inlet valves and the like contain a normally liquid fuel (usually a hydrocarbon fuel), a carboxylic acid ester of lubricating viscosity, and an oil-soluble nitrogen-containing dispersant. The dispersant is characterized by the presence therein of a substantially saturated hydrocarbon-based radical having at least about 50 carbon atoms, and it is preferably a carboxylic dispersant (e.g., the reaction product of a polyisobutenyl succinic acid-producing compound with a polyethylene polyamine) or a Mannich-type dispersant (e.g., the reaction product of an alkyl phenol with formaldehyde and a polyethylene polyamine).

  • Nitrile-amine reaction products
    Patent number: 4031015
    Abstract: Oil-soluble compositions made by reacting an olefin or halogenated olefin of about 30 carbon atoms with an alpha, beta-unsaturated nitrile to form an organonitrile intermediate and further reacting said intermediate with a nitrogen compound such as an amine or polyamine are useful as additives for lubricants and liquid fuels. Particularly useful additives are made from alkylene polyamines.

  • Ester-containing process and compositions
    Patent number: 4031118
    Abstract: Ester-containing compositions prepared by reacting a high molecular weight carboxylic acid acylating agent with polyoxyalkylene alcohol demulsifiers for aqueous emulsions. The ester-containing compositions are useful as additives in normally liquid fuels and lubricants.
