    • n toluene Methyl benzene (C6H5.CH3), a hydrocarbon forming a colorless mobile liquid having the odor of benzene, and of specific gravity 0.883 at 32° F. It is soluble to some extent in alcohol, ether, and fixed and volatile oils, and dissolves iodine, sulphur, and many resins. It is obtained by the dry distillation of tolu and many other resinous bodies, by the action of potash on benzylic alcohol, and by heating toluic acid with lime. Also toluol.
