| Use | protective fungicide, low toxicity, no systemic action. For seed detoxification and soil treatment, the mechanism of sterilization is to affect the mitosis of hyphal cells. 40% G seed dressing with 40% powder; G seed dressing with powder for controlling cotton seedling disease; Control of Sclerotinia sclerotiorum, 40% G of 1.5 powder per hundred square meters, mixed with 50% ~ 3kg of fine soil, scattered near the roots at the early stage of the disease; 375g of wettable powder per hundred square meters for prevention and control of potato scab, the strips were applied in the sowing ditch. excellent soil fungicide, used as seed dressing agent and soil treatment agent, for the prevention and control of cotton seedling blight, quakeproof disease, wheat, sorghum sput, potato scab, Ganlan root swollen disease, lettuce gray mold, etc. Spraying can control rice sheath blight. used as a seed dressing agent and soil treatment agent for the prevention and control of cotton seedling blight, anthracnose, wheat head smut, loose smut, vegetable sudden cross disease, garlic white rot and so on used in the selection and application of antibiotics, solubility, solution stability and other studies |
| production method | with iodine as catalyst, chlorosulfonic acid as solvent, 2,4, 5-trichloronitrobenzene reacts with chlorine at 80-85 °c. The solvent chlorosulfonic acid is used in an amount of 1-3 times the weight of trichloronitrobenzene, the iodine is used in an amount of 0.2-0.3% of the weight of trichloronitrobenzene, and the chlorine is passed to an excess of 1%. Then cooled to 30 ° C., pentachloronitrobenzene was filtered off, washed with 80-90 ° C. Hot water to neutral, and dried at 70 ° C. To obtain a product with a content of 98-99% in a yield of 94%. 2,4, 5-trichloronitrobenzene is obtained by nitration of 1,2,4 trichlorobenzene. The above method consumes iodine and chlorosulfonic acid, and the equipment is easy to corrode. The other production method is to use the trichlorobenzene embedded nitration and chlorination obtained from the Six Six Six non-toxic body, A raw powder with a chloronitrobenzene content of more than 70% can be obtained. Raw material consumption quota: trichlorobenzene (98%)880kg/t, liquid chlorine 930kg/t, sulfuric acid (100%)1020kg/t, nitric acid (98%)350kg/t, chlorosulfonic acid (more than 90%) 1100kg/t. 1,2, 4-trichlorobenzene was nitrated to give trichloronitrobenzene. Then chlorosulfonic acid as solvent, iodine as catalyst, 80~85 deg C through chlorine, chlorination of pentachloronitrobenzene. |
