Storage method

Storage Precautions[16] Store in a cool, well-ventilated special warehouse, and implement the “two people to send and receive, and two people to keep” system. Keep away from fire and heat sources. Keep container tightly sealed. They should be stored separately from oxidants, reducing agents, acids, and food chemicals, and avoid mixed storage. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

Main raw materials: trinitrophenol, calcium hydroxide, chlorine. Add lime to water in a certain proportion to prepare lime slurry, then mix a certain amount of lime, trinitrophenol, and water to make calcium salt and send it to the chlorination kettle, add lime slurry, and pass chlorine for about 2 hours under freezing. The temperature is controlled at 32±1°C, and then cooled to 7±1°C. After chlorination, it is distilled.

Purpose

1. This product is an alert fumigant that can kill insects, bacteria, and mice. It can also be used for fumigation of food pests. It can also be used for wood preservation, house floors, ship disinfection, soil, and plants. Seed disinfection, etc.

2. Used in organic synthesis to manufacture dyes, pesticides, fungicides, etc. [17]
