     Crude synthol rectified to 200° gave 87% of distillate suitable as light fuel having d20, 0.8289%; C2 69.29%; H2, 12.25%, calorific value, 8,200 cal./kg.; the cold test begins to set at –30° and is completely solidified at –90°.  Road tests with a 4-hp. motorcycle having a carburetor adjusted for C6H6 and running at 25 km./hr. showed the following distances/100 cm.3 of fuel:  C6H6, 2.9 km.; synthol 3; 1:1 C2H6-synthol 3.2, 1:1:1 C6H6-alcohol-synthol 2.9.  With synthol alone the motor knocks, but with synthol-C6H6 it runs quite smoothly.
