Used mainly in

As a key intermediate of the fungicide benzoxazole, it is used for the preparation of triazole fungicides.

Widely used as an intermediate in pharmaceuticals and pesticides.

Can be used for spice preparation, such as soap spices and rose shaped mixed spices.

It can also be used as a synthetic resin, organic high-temperature heat carrier, and other applications

Synthesis lines:

Using 1,3-dichlorobenzene and 4-chlorophenol as raw materials, potassium carbonate and basic copper carbonate catalyst were added to N-methylpyrrolidone (NMP) solvent, and the reaction was carried out at 170-173 ℃for several hours. Subsequently, the product was obtained by cooling, filtering, hydrochloric acid acidification (pH=6-6.5), dehydration, and vacuum distillation (2 kPa).

The reaction equation can be simplified as:

1,3-Dichlorobenzene+4-chlorophenol →3,4 '- Dichlorodiphenyl ether
