Take the amount and identify it with alcohol solution of silver nitrate. Benzyl chloride produces white precipitate immediately, chlorocyclohexane produces white precipitate after a period of time or heating, and chlorobenzene cannot produce white precipitate.

Properties and stability of chlorobenzene

1, chemical properties: stable, free from air, moisture and light under normal temperature and pressure, and will not decompose after long-term boiling. It does not react with steam, alkali, hydrochloric acid and dilute sulfuric acid at room temperature. When chlorobenzene vapor passes through red-hot platinum wire or iron pipe, 4,4'-dichlorobiphenyl, biphenyl and 4- chlorobenzene are generated.

React with sodium hydroxide solution at high temperature and high pressure, or react with water vapor in the presence of catalyst at normal pressure to hydrolyze into phenol. It does not react with ammonia, but reacts with concentrated ammonia to produce aniline at high temperature and high pressure in the presence of copper catalyst. The mixture of concentrated nitric acid and concentrated sulfuric acid was nitrated at 0℃, and the ratio of p-chloronitrobenzene to o-chloronitrobenzene was 7: 3.

Sulfonation reaction is easy to occur with hot concentrated sulfuric acid, and p-chlorobenzene sulfonic acid is generated. Benzene and biphenyl are produced by hydrogenation and reduction with nickel as catalyst, and biphenyl is also produced by reaction with sodium or sodium amalgam in the presence of boiling alcohol. The mixture of o-dichlorobenzene and p-dichlorobenzene was produced by chlorination with ferric chloride as catalyst.

Heating with bromine mainly produces p-bromochlorobenzene. Reacting with molten aluminum tribromide to generate bromobenzene. The reaction with iodine is very slow. Fluorobenzene will not be produced with general fluorinating agent. In the presence of fuming sulfuric acid, dichlorodiphenyltrichloroethane (DDT) is condensed with chloral.
