2ethyltoluene

2-ethyltoluene is an aromatic hydrocarbon belonging to the class of alkylbenzenes, characterized by a benzene ring with an ethyl group (–CH₂CH₃) and a methyl group (–CH₃) attached. It is a colorless liquid with a mild aromatic odor, often used as a solvent and intermediate in chemical synthesis. The compound has the chemical formula C₉H₁₂ and falls under the broader category of xylenes and ethylbenzenes, differing primarily in its substituent arrangement.

2-ethyltoluene is typically produced through catalytic alkylation of toluene with ethylene, a process commonly employed in industrial settings. It is a component of certain petroleum fractions and can be separated via fractional distillation. Due to its structural similarity to other alkylbenzenes, it shares some physical properties, such as low solubility in water and higher density than water.

Applications of 2-ethyltoluene include use as a solvent in coatings, adhesives, and inks, as well as a precursor in the manufacture of pharmaceuticals, agrochemicals, and specialty chemicals. It may also serve as a diluent in paint formulations or as a blending agent in fuels. Like many aromatic compounds, it exhibits moderate volatility and can evaporate readily at room temperature.

Safety considerations for 2-ethyltoluene include its potential to irritate skin, eyes, and respiratory tract upon prolonged exposure. Proper ventilation and protective equipment are recommended when handling the substance. Environmental regulations may apply to its disposal, as it can contribute to air pollution if released into the atmosphere. Toxicity data suggests it is generally low in acute toxicity but may require further study for long-term effects.
