toluene
toluene or methylbenzene , C 7 H 8 , colorless liquid aromatic hydrocarbon that melts at -95°C and boils at 110.8°C. It is insoluble in water but highly soluble in most organic solvents. Toluene is obtained from coal tar and petroleum by distillation. It is used as a solvent and as a starting material for the synthesis of many compounds, including dyes and explosives. When toluene is treated with a mixture of nitric and sulfuric acids (a process known as nitration), trinitrotoluene (TNT) is produced. |
