Abstract
An amido alkanolamine composition obtained by reacting, at a temperature of 10.degree. C.-200.degree. C.: (a) a 4-alkyl-2-morpholinone represented by the formula: ##STR1## in which R represents a monovalent aliphatic radical having from 1 to 10 carbon atoms, and (b) a hydrocarbyl oxypolyoxyalkylene amine represented by the formula: ##STR2## in which R' represents an alkyl, an alicyclic, or a alkylalicyclic radical having from 8 to 30 carbon atoms, x has a value from 5 to 50, and R" represents a methyl radical or a mixture of hydrogen and methyl radicals is provided.
Claims11
An amido alkanolamine composition obtained by reacting, at a temperature of 10.degree. C.-200.degree. C.:
- (a) a 4-alkyl-2-morpholinone represented by the formula:
- ##STR18## in which R represents a monovalent aliphatic radical having from 1 to 10 carbon atoms, and
- (b) a hydrocarbyl oxypolyoxyalkylene amine represented by the formula:
- ##STR19## in which R' represents an alkyl or an alicyclic radical having from 8 to 30 carbon atoms, x has a value from 5 to 50, and R" represents a methyl radical or a mixture of hydrogen and methyl radicals.
A fuel composition containing from about 0.00015 to 1 weight percent of an amino reaction product prepared by reacting a 4-alkyl-2-morpholinone represented by the formula:
- ##STR20## in which R represents a monovalent aliphatic radical having from 1 to 10 carbon atoms, with an alkoxypolyoxyalkylene amine reactant represented by the formula:
- ##STR21## in which R' represents a hydrocarbyl radical having from 8 to 30 carbon atoms, R" represents a methyl radical or a mixture of hydrogen and methyl radicals, and x has a value from 5 to 50.
A fuel composition according to claim 10 in which said fuel is a mixture of hydrocarbons in the gasoline boiling range.
A method for preparing an amido alkanolamine composition represented by the formula:
