Trichlorfon is a low toxicity, insecticidal spectrum of organic phosphorus insecticide. Appearance is white crystal. In the weak alkaline solution can become dichlorvos, but unstable, and soon break down. Pests have a strong stomach poisoning effect, both the role of contact with the plant has a permeability. It is suitable for the control of insects, such as rice, wheat, vegetables, tea trees, fruit trees, mulberry trees, cotton and green berries. It can also be used in a large number of livestock parasites, sanitary pests and fish parasites and fish. Prevention and treatment of egg pests. |
| Physical and chemical properties: |
Pure white crystal, aldehyde odor. Melting point (° C): 83 to 84 Boiling point (° C): 100 (13.33 kPa) Relative density (water = 1): 1.73 Saturated vapor pressure (kPa): 13.33 (100 ° C) Solubility: Solubility Water (20 ° C) L, soluble in most organic solvents, but insoluble in aliphatic and petroleum, hexane 0.1-1, dichloromethane, isopropyl alcohol> 200, toluene 20-50 (g / L, 20 ℃), easy hydrolysis and Hydrogen chloride reaction, heating, & gt; pH6 decomposition quickly, slow photolysis. Alkali is quickly converted to dichlorvos, 22 ° C hydrolysis, the half-life with the increase in pH and shorten. |
