Abstract 1. A KNOCK-RESISTANT LEADED GASOLINE COMPOSITION FOR USE IN SPARK IGNITION ENGINES, SAID COMPOSITION COMPRISING (1) GASOLINE CONTAINING PARAFFINIC HYDROCARBON CONTENT OF NOT MORE THAN 95% BY VOLUME AND A MINIMUM RESEARCH OCTANE NUMBER OF ABOUT 90; (2) A LEAD AKYL ANTIKNOCK ADDITIVE IN AN AMOUNT FROM ABOUT 0.5 TO ABOUT 6.0 CC. PER GALLON OF SAID GASOLINE; AND (3) A SMALL AMOUNT, SUFFICIENT TO EXTEND TO ANTIKNOCK EFFECT OF LEAD IN SAID GASOLINE, OF A GASOLINE-DISPERSIBLE, NON-CORROSIVE TERTIARY ALCOHOL ESTER OF A MONOCARBOXYLIC ACID CONTAINING ONLY CARBON, HYDROGEN AND OXYGEN IN ITS MOLECULAR STRUCTURE, SAID ESTER BEING INERT WITH RESPECT TO LEAD ALKYLS AT TEMPERATURES UP TO ABOUT 40*C., BEING PRESENT IN SAID LEADED GASOLINE IN A CONCENTRATION FROM ABOUT 3 TO ABOUT 60 MOLES PER GRAM-ATOM OF LEAD IN THE GASOLINE.
