Properties and stability
Does not decompose under normal 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 corresponding varieties and
Amount of fire equipment. Suitable materials should be available in the storage area to contain spills. The management system for extremely toxic substances “five pairs “ should be strictly implemented.
Synthesis method
The dimerization reaction of isobutylene, sodium nitrite and hydrochloric acid produces 2-chlorine-2-methyl-1-nitrosopropane dimer. The dimer reacts with sodium methylthiolate to produce 2-methyl -2- (methylthio) propionaldehyde oxime . Finally, the oxime reacts with methyl isocyanate to prepare aldicarb.
Purpose
Used as agricultural pesticide.
