<p>A gasoline additive comprising at least one nitrogenous compound selected among polyoxyalkyleneamine compounds (1A) and polybutenylamine compounds (1B). It gives a gasoline composition suitable for use in direct-injection gasoline engines. The compounds (1A) can be obtained by using an appropriate ketimine compound as a reaction initiator to polymerize an epoxy compound and hydrolyzing the resultant polyoxyalkylene glycol derivative.</p> |
