1-Chloro-4-ethylbenzene - Introduction
1-Chloro-4-ethylbenzene is an organic compound with the chemical formula C8H9Cl. In the structure, one hydrogen on the benzene ring is replaced by a chlorine atom, and an ethyl group is attached to the benzene ring.
1-Chloro-4-ethylbenzene is a colorless liquid with a fragrance. It has a density of 0.99 g/mL, a boiling point of 199-202°C, and a melting point of -38°C. It is soluble in organic solvents such as ether and chlorinated hydrocarbons and insoluble in water.
1-Chloro-4-ethylbenzene is mainly used as an intermediate in organic synthesis. It can be used to synthesize other organic compounds, such as pesticides, drugs, dyes and fragrances. In addition, it can also be used as an organic solvent, a surfactant, and the like.
1-Chloro-4-ethylbenzene is prepared by chlorinating benzene and ethylene. A common method is to first react benzene with chlorine to produce chlorobenzene (C6H5Cl), and then aromatic substitution reaction of chlorobenzene with ethylene to produce 1-Chloro-4-ethylbenzene.
Regarding safety information, 1-Chloro-4-ethylbenzene is a flammable liquid that can cause combustion when exposed to open flames or high temperatures. Avoid contact with skin, eyes and respiratory tract during operation. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help. During storage and handling, attention should be paid to fire and explosion prevention measures to ensure good ventilation.
