1ethyl3methylbenzene

1-Ethyl-3-methylbenzene, also known as 1-ethyl-3-xylene, is an organic compound with the chemical formula C9H12. It is an isomer of xylene, a group of aromatic hydrocarbons that are widely used as solvents in the chemical industry. 1-Ethyl-3-methylbenzene is a clear, colorless liquid with a mild, aromatic odor. It is slightly soluble in water but miscible with most organic solvents.

The compound is primarily used as a solvent in the production of synthetic fibers, plastics, and other chemical products. It is also used as a raw material in the synthesis of various pharmaceuticals and agrochemicals. In the laboratory, 1-ethyl-3-methylbenzene is used as a reagent in organic synthesis.

The synthesis of 1-ethyl-3-methylbenzene typically involves the alkylation of toluene with ethylene. The reaction is usually catalyzed by a strong acid, such as sulfuric acid or hydrochloric acid. The product is then purified by distillation or other separation techniques.

1-Ethyl-3-methylbenzene is a flammable liquid and should be handled with care. It is also toxic if ingested or inhaled, and can cause skin and eye irritation. Proper safety measures, including the use of personal protective equipment and ventilation, should be taken when handling the compound.
