    摘要: Polyalkyl and polyalkenyl aromatic amides having the formula: ##STR1## or a fuel-soluble salt thereof; wherein A is hydroxy, nitro, amino, N-alkylamino wherein the alkyl group contains 1 to 6 carbon atoms, or N,N-dialkylamino wherein each alkyl group independently contains 1 to 6 carbon atoms; R.sub.1 and R.sub.2 are each independently hydrogen, hydroxy, lower alkyl having 1 to 6 carbon atoms, or lower alkoxy having 1 to 6 carbon atoms; R.sub.3 is hydrogen or lower alkyl having 1 to 6 carbon atoms; R.sub.4 is hydrogen or an acyl group of the formula: ##STR2## wherein A.sub.1 is hydroxy, nitro, amino, N-alkylamino wherein the alkyl group contains 1 to 6 carbon atoms, or N,N-dialkylamino wherein each alkyl group independently contains 1 to 6 carbon atoms; R.sub.6 and R.sub.7 are each independently hydrogen, hydroxy, lower alkyl having 1 to 6 carbon atoms, or lower alkoxy having 1 to 6 carbon atoms; R.sub.5 is a polyalkyl or polyalkenyl group having an average molecular weight in the range of about 450 to 5,000; n is an integer from 0 to 2; and x is an integer from 2 to 5.The polyalkyl and polyalkenyl aromatic amides of formula I are useful as fuel additives for the prevention and control of engine deposits.
