ABSTRACT:
Substituted biphenyl polyalkyl esters having the formula: ##STR1## wherein R.sub.1 is hydrogen or hydroxyl; R.sub.2 is hydroxyl, cyano, nitro, amino, aminomethyl, N-alkylamino or N-alkylaminomethyl wherein the alkyl group contains 1 to about 6 carbon atoms, N,N-dialkylamino or N,N-dialkylaminomethyl wherein each alkyl group independently contains 1 to about 6 carbon atoms, with the proviso that R.sub.1 and R.sub.2 are ortho relative to each other and meta or para relative to the adjoining phenyl substitutent; and R.sub.3 is a polyalkyl group having an average molecular weight in the range of about 450 to about 5,000.
The substituted biphenyl polyalkyl esters of the present invention are useful as fuel additives for the prevention and control of engine deposits.
