Abstract
A gasoline deposit control additive composition for use in a fuel comprising from about 70 to about 95 volume percent of hydrocarbons in the gasoline boiling range and from about 5 to about 30 volume percent of at least one alcohol, comprising the imine or tertiary amine product of the reaction between (a) at least one aldehyde or ketone or mixture thereof having the formula R16 CHO, R16 CH2 CHO, R17 (C=0) R18 or R17 CH2 (C=0) R18, wherein R16, R17, and R18 are the same or different and are each independently a straight or branched chain hydrocarbyl or aryl group that contains from 1 to 18 carbon atoms, and (b) a primary or secondary amine functionality.
Claims11
A liquid automotive fuel comprising from about 70 to about 95 volume percent of hydrocarbons boiling in the gasoline range, from about 5 to about 30 volume percent of at least one alcohol, and an imine or tertiary amine product of the reaction between
- (a) at least one aldehyde having the formula R16 CHO or R16 CH2 CHO, wherein R16 is a straight or branched chain hydrocarbyl or aryl group that contains from 1 to 18 carbon atoms, and
- (b) a primary or secondary amine functionality of the formula:
- wherein:
- R4 is nitro or —(CH2)n—NR9R10, wherein R9 and R10 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms and n is 0 or 1;
- R5 is hydrogen, hydroxy, nitro or —NR11 R12, wherein R11 and R12 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms;
- R6 and R7, are independently hydrogen or lower alkyl having 1 to 6 carbon atoms;
- and R8 is a polyalkyl group having an average molecular weight in the range of about 450 to 5,000.
