Abstract

A particularly useful low lead aviation gasoline fuel blend complies with all requirements of ASTM D 910 and includes 67.0 volume % isooctane, 18.0 volume % xylene, 12.0 volume % isopentane, 3.0 volume % isobutane and 0.47 mL/gal of tetraethyl lead. Another useful low lead aviation gasoline fuel blend which complies with all requirements of ASTM D 910 except for oxygenate content includes 60.0 volume %
isooctane, 15.0 volume % xylene, 14.0 volume % methyl t-butyl ether, 8.0 volume %
isopentane, 3.0 volume % isobutane and 0.2 mL/gal of tetraethyl lead. The isooctane used in either case is a purified isooctane prepared either by fractionating a crude DIB
material and hydrogenating the fractionated material or hydrogenating the crude DIB
material and fractionating the hydrogenated material.
