Polyoxyalkylenpolylaktoneaminocarbamate, und dieselben enthaltende Kraftstoffzusammensetzungen

摘要

Polyoxyalkylene polylactone aminocarbamates having the formula: wherein R1 is a hydrocarbyl group having a sufficient number of carbon atoms to render the compound soluble in hydrocarbons boiling in the gasoline or diesel fuel range; R2 and R3 are each independently hydrogen or lower alkyl having about 1 to about 6 carbon atoms and each R2 and R3 is independently selected in each -O-CHR2-CHR3- unit; R4 is an alkylene group of about 2 to about 5 carbon atoms; A is a polyamine moiety having at least one basic nitrogen atom; x is an integer from about 1 to about 100; and y is an integer from about 1 to about 25. The polyoxyalkylene polylactone aminocarbamates of formula I are useful as fuel additives for the prevention and control of engine deposits.
