Specific application
Pesticide intermediates; It is used as an intermediate of puma, high efficiency Gaicao, jingwensha, jingquizalofop, alkyne ester and other herbicides

Production method
1. P-chlorobenzoyl chloride was prepared by the reaction of p-chlorobenzoyl chloride with anisole, followed by hydrolysis and demethylation.
2. Reaction of p-chlorobenzoyl chloride with phenol: dissolve 9.4g (0.1mol) of phenol in 4ml of 10% sodium hydroxide solution, add 14ml (0.110mol) of p-chlorobenzoyl chloride dropwise at 40 ~ 45 ℃, add it within 30min, and react at the same temperature for 1H. Cool to room temperature, filter and dry to obtain 22.3g of phenyl p-Chlorobenzoate. The yield is 96%, and the melting point is 99 ~ 101 ℃.

Leakage emergency treatment
Protective measures, protective equipment and emergency disposal procedures for operators:
It is recommended that emergency treatment personnel wear air breathing apparatus, anti-static clothes and rubber oil resistant gloves.
Do not touch or cross spills.

Small leakage: collect the leakage liquid in a sealable container as far as possible. Absorb with sand, activated carbon or other inert materials and transfer to a safe place. Do not flush into the sewer.
Massive leakage: build a dike or dig a pit for reception. Close the drainage pipe. Foam is used to cover evaporation. Transfer to tank car or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.
Personal protective equipment:
Respiratory protection: when the concentration in the air exceeds the standard, wear filter gas mask (half mask). When rescuing or evacuating in an emergency, you should wear an air breathing apparatus.
Hand protection: wear rubber oil resistant gloves.
