Orthotoluene

Orthotoluene, also known as o-toluene or 1-methylbenzene, is an organic compound with the chemical formula C7H8. It is one of the three isomeric forms of toluene, with the others being metatoluene (m-toluene) and paratoluene (p-toluene). In orthotoluene, the methyl group (CH3) is attached to one of the carbon atoms ortho to the benzene ring, specifically at the 2-position.

Orthotoluene is a colorless liquid with a sweet, aromatic odor. It is slightly soluble in water but miscible with most organic solvents. The compound is primarily used as a precursor in the synthesis of various chemicals, including pharmaceuticals, dyes, and other organic compounds. It is also used as a solvent in some industrial processes.

The synthesis of orthotoluene typically involves the methylation of benzene using a methylating agent, such as methyl chloride or dimethyl sulfate, in the presence of a catalyst. The resulting mixture of isomeric toluenes can be separated using fractional distillation or other purification techniques.

Orthotoluene is a flammable liquid and should be handled with care. It is also classified as a hazardous substance, and appropriate safety measures should be taken when handling or storing the compound.
