Abstract
Abstract A GASOLINE MOTOR FUEL HAVING IMPROVED ANTI-ICING, DETERGENCY, ANTI-RUST AND IGNITION CONTROL CHARACTERISTICS IS OBTAINED BY INCORPORATION IN THE FUEL A SMALL AMOUNT OF A COMBINATION OF A POLYOXYPROPYLENE ESTER AND A MONOCARBOXYLIC ACID SALT OF AN N-ALIPHATIC SUBSTITUTED POLYMETHYLENE DIAMINE. THE POLYOXYPROPYLENE ESTER HAS THE GENERAL FORMULA RCOOC3H6O(C3H6O)NC3H6OH WHERE R IS AN ALIPHATIC HYDROCARBON RADICAL CONTAINING 7 TO 29 CARBON ATOMS AND N IS AN INTEGER OF 20 TO 100. THE MONOCARBOXYLIC ACID SALT IS THE SALT OF A MONOCARBOXYLIC ACID WHICH CONTAINS AT LEAST 8 CARBON ATOMS IN THE MOLE CULE AND AN N-ALIPHATIC SUBSTITUTED POLYMETHYLENE DIAMINE WHICH HAS THE GENERAL FORMULA RNH (CH2) XNH2 WHERE R IS AN ALIPHATIC HYDROCARBON RADICAL CONTAINING 8 TO 30 CARBON ATOMS AND X IS AN INTEGER OF 2 TO 10.
