Toxicity | LD50 orally in rats: 700 mg/kg (Magee, 1973) |
pure white crystals. Soluble in water, methanol, acetone and other polar solvents and dichloromethane, dichloroethane and other halogenated alkanes, benzene, toluene, xylene solubility is smaller, less soluble in ether. Unstable in alkaline medium.
methyl chloride, ammonia, dichloroethane, acetic anhydride, dimethyl sulfate as raw materials. Acephate was prepared by amination, acylation and isomerization. That is, 0,O dimethyl thiophosphoramide is obtained by amination, and 0.0 dimethyl-N-acetyl thiophosphoramide is obtained by acylation, and acephate is obtained by isomerization reaction.
is a broad-spectrum insecticide against rice pests, planthopper, leaf hopper, thrips, armyworm, Chilo suppressalis, Cotton aphids, cotton bollworm, fruit tree of the pear picolea, peach, spodoptera litura, cabbage worm, wheat aphid, armyworm and so on have good control effect.
rat oral LD50: 700mg/kg.
