Nature description: Appearance is white crystal. The melting point is 63-64°C. The solubility in water is 0.5%, and it can be dissolved in most organic solvents. Production method: Direct condensation of chloroacetylmorpholine and O, O-dimethyl dithiophosphate sodium And get. Process conditions: The ingredient ratio is O, O-dimethyl dithiophosphate sodium: chloroacetylmorpholine = 1.05-1.10 (molar ratio). Add O, O-dimethyl sodium dithiophosphate to the reaction flask, cool in an ice bath, add morpholine (more than 30%) when the material temperature drops below -8°C, and keep the temperature below -5°C. Chloroacetyl chloride was added dropwise, and when the pH value was close to 7, liquid caustic soda was immediately added dropwise. After the chloroacetyl chloride was dropped, the reaction was stirred at -8°C for 1 h. Then add benzene, stir and react at 50-60°C for 1h, cool down, let it stand, separate the benzene layer, and distill under reduced pressure to obtain Maoguo. Formulated as 25% emulsion or powder. Application: Maoguo has the characteristics of strong systemic absorption, high efficiency and low toxicity, and is mainly used to control cotton aphids , cabbage aphid, cotton spider mite, cotton thrips and other pests, its efficacy is similar to that of dimethoate.
