Purpose:
Uses of o-chlorobenzonitrile:
Medicine: mainly used for the synthesis of anti-malarial new drugs nitroquine and a variety of anti-inflammatory bactericidal drugs, for the preparation of non-peptide anti-angiotensin and other main; Dyes: mainly used for the synthesis of dye intermediates 2-cyano-4-nitroaniline; Corrosion inhibitor for carbon steel.

Preparation method:
The o-chlorotoluene is measured and passed into the o-toluene carburetor. The liquid ammonia oil cylinder is vaporized under reduced pressure and is metered into the ammonia heater by the flow meter. The air is raised by the air compressor and then measured by the flow meter, and enters the reactor with o-chlortoluene and ammonia. After the reaction, the o-chlorobenzonitrile product is captured by the trap, while the tail gas and waste water enter the three waste treatment section.

Purpose:
Intermediates of organic synthesis. It is mainly used in the synthesis of dye intermediates 2-cyano-4-nitroaniline, and is used in the pharmaceutical industry for the synthesis of new anti-malarial drugs such as nitroquine.
