This method describes a process for the separation of tetraethyllead and tetramethyllead when both are present in a gasoline blend. It also provides a qualitative test to confirm the suspected presence or absence of either of these compounds or the mixed alkyl lead antiknock compounds in gasoline blends or other volatile distillates. The sample is separated into two fractions by distillation after dilution with a xylene-toluene mixture. The distillate or fraction that distills below 133/sup 0/C contains the tetramethyllead and the more volatile portions of the mixed lead alkyls; the residue or fraction that distills above 133/sup 0/C contains the tetraethyllead and the less volatile portion of the mixed lead alkyls. The lead in each fraction is determined by either method for lead in gasoline: ASTM Method D 3237, Method D 3341, and Method D 2547.
