4ethyltoluene

4-Ethyltoluene is an organic compound with the chemical formula C9H12. It is a colorless liquid at room temperature and is a member of the aromatic hydrocarbon family, specifically a substituted toluene. Its structure consists of a benzene ring with a methyl group and an ethyl group attached at opposite positions (para substitution).

This compound is primarily used as a chemical intermediate in the synthesis of other organic compounds. It can be involved in reactions such as oxidation to form 4-ethylbenzoic acid or further alkylation. 4-Ethyltoluene is also a component of some industrial solvents and can be found in certain fuel mixtures, though its presence is often incidental rather than intentional.

The production of 4-ethyltoluene typically involves the alkylation of toluene with ethylene or ethanol in the presence of a catalyst. It can also be obtained from coal tar distillation. Due to its aromatic nature and flammability, appropriate safety precautions are necessary when handling and storing 4-ethyltoluene. It is generally considered to have low acute toxicity, but prolonged or repeated exposure can lead to skin and respiratory irritation. Environmental release should be avoided as it can contribute to air pollution.
