Abstract:
The present disclosure provides fuel additives including a quaternary ammonium salt formed by reacting an alkyl carboxylate with a compound formed from a hydrocarbyl substituted acylating agent reacted with a select amine. Also provided herein are fuel compositions including the novel fuel additives and methods of combusting a fuel including the fuel additives herein. The unique quaternary ammonium salts herein are advantageous because they can be made through a simple alkylation process and provide improved detergency at low treat rates by making available a relatively less sterically hindered quaternary nitrogen for detergency activity in the fuel.

Claim (Index 20):
A method of  claim 18 , wherein the formed quaternary ammonium salt has the structure wherein\n A includes 2 to 6 carbon units with one carbon unit thereof independently replaced with \u2014O\u2014 or \u2014NH\u2014; \n R 1 , R 2 , and R 3  are independently alkyl groups containing 1 to 8 carbon atoms; and \n R 4  and R 5  are independently selected from a hydrogen, an acyl group, or a hydrocarbyl substituted acyl group, wherein if one of R 4  or R 5  is hydrogen, then the other of R 4  and R 5  is the acyl group or the hydrocarbyl substituted acyl group, if both R 4  and R 5  include carbonyl moieties, then one of R 4  and R 5  includes the acyl group and the other of R 4  and R 5  includes the hydrocarbyl substitued acyl group, and R 4  and R 5  together with the N atom to which they are attached, combine to form a ring moiety; and \n M \u2212  is a carboxylate.
