                  Liquid fraction, boiling 240°-300°, of synthine residue and the solid fraction requires 20% of AlCl₃ for cracking.  The solid-fraction boiling above 300° is cracked with only 10% of AlCl₃.  Maximum yields of gasoline up to 48% are obtained on cracking with 15% AlCl₃.  The gasoline obtained, boiling 22°-150°, consists nearly exclusively of isoparaffins.  The octane number of the 22°-50° fraction containing pentanes and hexanes is 88, of the 50°-100° fraction it is 73, and of the whole 22°-150° fraction it is 79.
