Properties and stability

Avoid contact with oxidizing agents.

Storage method

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. should be kept away from oxidizer, do not store together. Keep sealed. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

1. It is obtained by using thiophenol and dimethyl sulfate as raw materials and carrying out esterification reaction under alkaline conditions.

2. Aniline method: Diazonium salt is prepared by diazotization of aniline; it is then reacted with sodium methylmercaptide. The final reaction formula is as follows:


Purpose

In medicine, it is used as a raw material for the synthesis of antibiotics and anti-ulcer drugs; in pesticides, it is used as a raw material for the synthesis of insecticides, fungicides, and herbicides; it is also used as a stabilizer for vitamin A and an antioxidant for aromatic amines. , lubricating additives, raw materials for spice synthesis, etc.
