Abstract
Polyalkylphenoxyaminoalkanes having the formula: ##STR1## wherein R is a polyalkyl group having an average molecular weight in the range of about 600 to 5,000; R.sub.1 and R.sub.2 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms; and A is amino, N-alkyl amino having about 1 to about 20 carbon atoms in the alkyl group, N,N-dialkyl amino having about 1 to about 20 carbon atoms in each alkyl group, or a polyamine moiety having about 2 to about 12 amine nitrogen atoms and about 2 to about 40 carbon atoms. The compounds of formula I are useful as fuel additives for the prevention and control of engine deposits.
Claims63
A compound of the formula:
- ##STR18## or a fuel-soluble salt thereof, wherein R is a polyalkyl group having an average molecular weight in the range of about 600 to 5,000;
- R.sub.1 and R.sub.2 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms;
- and
- A is amino, N-alkyl amino having about 1 to about 20 carbon atoms in the alkyl group, N,N-dialkyl amino having about 1 to about 20 carbon atoms in each alkyl group, or a polyamine moiety having about 2 to about 12 amine nitrogen atoms and about 2 to about 40 carbon atoms.
A fuel composition comprising a major amount of hydrocarbons boiling in the gasoline or diesel range and an effective deposit-controlling amount of a compound of the formula:
- ##STR19## or a fuel-soluble salt thereof, wherein R is a polyalkyl group having an average molecular weight in the range of about 600 to 5,000;
- R.sub.1 and R.sub.2 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms;
- and
- A is amino, N-alkyl amino having about 1 to about 20 carbon atoms in the alkyl group, N,N-dialkyl amino having about 1 to about 20 carbon atoms in each alkyl group, or a polyamine moiety having about 2 to about 12 amine nitrogen atoms and about 2 to about 40 carbon atoms.
A fuel concentrate comprising an inert stable oleophilic organic solvent boiling in the range of from about 150.degree. F. to 400.degree. F. and from about 10 to about 70 weight percent of a compound of the formula:
- ##STR20## or a fuel-soluble salt thereof, wherein R is a polyalkyl group having an average molecular weight in the range of about 600 to 5,000;
- R.sub.1 and R.sub.2 are independently hydrogen or lower alkyl having 1 to 6 carbon atoms;
- and
- A is amino, N-alkyl amino having about 1 to about 20 carbon atoms in the alkyl group, N,N-dialkyl amino having about 1 to about 20 carbon atoms in each alkyl group, or a polyamine moiety having about 2 to about 12 amine nitrogen atoms and about 2 to about 40 carbon atoms.
