Storage method

Storage Precautions[24] Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 37℃. The packaging must be sealed and must not come into contact with air. They should be stored separately from oxidants and acids, and avoid mixed storage. 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

It can be separated from the by-product of propylene chloride produced from high-temperature chlorination of propylene. It can also be obtained by dehydrochlorination of 1,2,3-trichloropropane under the action of alkali.

Purpose

1. It can be mixed with dichloropropane as a soil fumigant, and can also be used as a chemical reagent and solvent to treat the soil before crop planting. It can prevent and control root-knot nematodes, short-body nematodes, cyst nematodes and other nematodes in various crops. and underground pests.

2. Used in organic synthesis and as an antifungal agent. [25]
