1, 4-dichlorobenzene is an organic compound. Its main properties are as follows:

Appearance and odor: 1, 4-dichlorobenzene is a colorless liquid with a benzene-like aromatic odor.

Solubility: 1, 4-dichlorobenzene is soluble in organic solvents such as alcohols, ethers and aromatic hydrocarbons, but insoluble in water.

Chemical reaction: 1, 4-dichlorobenzene is a common organic reagent that can undergo substitution reactions, such as reacting with nucleophiles to form corresponding substitution products.

Usage: 1, 4-dichlorobenzene is mainly applied in the field of organic synthesis:

Preservative: 1, 4-dichlorobenzene has certain preservative properties and can be used to preserve wood and coatings.

Solvent: Due to its excellent solubility, 1, 4-dichlorobenzene is often used as an organic solvent to dissolve other organic substances.

1, 4-dichlorobenzene can be produced by reacting benzene with chlorine. The specific preparation methods include:

Direct chlorination method: Chlorine gas is introduced into liquid benzene, and through chlorination reaction, 1, 4-dichlorobenzene is produced.

Indirect chlorination method: First, benzene reacts with nitrous acid to form benzene nitroso compounds, and then it undergoes chlorination to generate 1, 4-dichlorobenzene.

Safety Information: 1, 4-dichlorobenzene should be handled in a closed ventilation system to avoid inhaling its vapor. In case of contact with skin or eyes, rinse immediately with plenty of water. During use or storage, contact with oxidants and strong acids should be avoided to prevent reactions. It should be stored in a cool, dry and well-ventilated place, away from fire sources and high temperatures.
