Properties and stability
Stable at room temperature and pressure, avoid contact with strong oxidants and strong alkali.
Storage method
Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging is sealed. They should be stored separately from oxidants, alkalis, and food chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. Suitable materials should be available in the storage area to contain spills.
Synthesis method
Obtained from the chlorination of 1,4- naphthoquinone. The chlorination operation is carried out in acetic anhydride or dinitrobenzene or alcohols, phenols, hydrocarbon solvents, and the catalyst is bromine or iron powder and ferric chloride. It can also be prepared from 1, 4- amino naphthalene sulfonic acid diluted in 50% In sulfuric acid solution, using iron as a catalyst, family: 宋体”>℃Obtained by chlorination.
Purpose
Used as agricultural fungicide.
