Dichlorvos

Dichlorvos / CAS : 62-73-7

Appearance An aromatic colorless to amber liquid, which is soluble in most organic solvents such as benzene and xylene, insoluble in petroleum ether and kerosene, and has a solubility of about 0.6% ~ 1% in water. The technical drug has good thermal stability, does not decompose after long-term storage, but is easy to hydrolyze. The hydrolysis rate of saturated dichlorvos aqueous solution at room temperature is about 3% per day. Under alkaline or heating conditions, the hydrolysis is accelerated. It is corrosive to iron and steel and resistant to stainless steel, aluminum, nickel, Hastelloy and Teflon. UN 2786
