Abstract: TETRAMETHYLLEAD IN CONCENTRATED FORM, ESPECIALLY WHEN UNDER CONFINEMENT, IS STABILIZED AGAINST PRONOUNCED THERMAL DECOMPOSITION AT ELEVATED TEMPERATURE BY MAINTAINING IT IN INTIMATE CONTACT WITH SUITABLE AMOUNTS OF CERTAIN HYDROCARBONS (B.PB CA. 90-150* C.) SUCH AS TOULENE AND ISOOCTANE. EQUIMOLAR TETRAMETHYLLEAD-ETHYLENE DIBROMIDE CONCENTRATES VIOLENTLY EXPLODED WHEN HEATED UNDER CONFINEMENT TO 295-305*C. INCLUSION OF THE HYDROCARBON IN APPROPRIATE CONCENTRATIONS, IN SOME CASES WITH ETHYLENE DICHLORIDE REPLACING PART OF THE ETHYLENE DIBROMIDE, ELIMINATED THIS EXPLOSIVE DECOMPOSITION AND RAISED THE TEMPERATURE AT WHICH PRONOUNCED, NONEXPLOSIVE THERMAL DECOMPOSITION COMMENCED.
