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.
