Claim 1

A HALOGEN SCAVENGER-FREE ALKULLEAD COMPOUND NORMALLY SUSCEPTIBLE TO RAPID DECOMPOSITION AT TEMPARATURES IN THE RANGE OF 180-195* C. HAVING ADMIXED THEREWITH (1) A MIXTURE OF FUSED RING AROMATIC HYDROCARBONS, SAID MIXTURE BEING CHARACTERIZED IN THAT IT CONTAINS AT LEAST 2 DIFFERENT FUSED RING AROMATIC HYDROCARBONS AT LEAST ONE OF WHICH IS PRESENT TO THE EXTENT OF AT LEAST 5 PERCENT BY WEIGHT OF THE OTHER, IN THAT SAID HYDROCARBONS HAVE BOILING POINTS AT ATMOSPHERIC PRESSURE OF AT LEAST ABOUT 180* C. IN THAT SAID HYDROCARBON CONTAIN UP TO ABOUT 20 CARBON ATOMS IN THE MOLECULE, AND IN THAT AT LESAT 2 OF SAID HYDROCARBONS DIFFER FROM EACH OTHER IN CARBON CONTENT BY AT LEAST ONE CARBON ATOM; AND (2) A SATURATED LOWER ALIPHATIC MONOHYDRIC ALCOHOL HAVING THE FORMULA ROH WHEREIN R IS A LOWER ALKYL GROUP; THERE BEING PRESENT FROM ABOUT 2 TO ABOUT 30 PERCENT OF SAID HYDROCARBONS AND FROM ABOUT 1 TO ABOUT 25 PERCENT OF SAID ALCOHOL SUCH THAT THE TOTAL AMOUNT OF SAID HYDROCARBONS PLUS SAID ALCOHOL IS IN RANGE OF ABOUT 3 TO ABOUT 45 PERCENT AND SUFFICIENT TO INHIBIT SUCH DECOMPOSITION, ALL PERCENTAGES BEING BY WEIGHT AND BEING BASED ON THE WEIGHT OF SAID COMPOUND.
