toxicity | the original drug has acute oral LD50 of 2000 ~ 8600mg/kg in rats and 1960 ~ 2800mg/kg in mice. Acute percutaneous LD50>3000 mg/kg in rats; The LD50 injected intraperitoneally into rats was 763 mg/kg. Acute inhalation of LC50>3960mg/l in rats. There was no irritation to rabbit skin and eyes, no abnormality was found in guinea pig sensitization test, and no effective dose in animal feeding test for two years: 36.5mg/(kg d) for rats, 54.1mg/(kg d) for mice, and 70mg/(kg d) for dog feeding for one year. No carcinogenic, teratogenic and mutagenic effects were found in animal test. Carp LC50 is 234.6mg/L (96h), rainbow trout LC50 is 409.9~616mg/L (96h), blue gill sunfish 415.0mg/L, safe for bees and low toxicity to earthworms. |
use | systemic fungicide, suitable for foliar treatment, soil treatment and seed treatment. It is effective against algae fungi. For example, the diseases caused by the true grate such as Mycobacterium, Trichosanthes, Phytophthora, Phytophthora, Pseudofrost, Pythium, etc. have a control effect, and can stimulate the growth of plants. The soil treatment was irrigated with 400~600 times of 72.2% water solution, and the foliar treatment was sprayed with 600~1000 times of liquid before the onset of the disease, spraying once every 7~10 days. is a high-efficiency, broad-spectrum and safe carbamate fungicide It is a high-efficiency fungicide with local internal absorption. It can be used for stem and leaf treatment, soil treatment and seed treatment to prevent and control a variety of crops caused by frost mold fungi. |
production method | acrylonitrile is added into a three-port flask, heated to an appropriate temperature in a water bath, dimethylamine gas is introduced, and β-dimethylamino propiononitrile is obtained by reacting for 1h. Then β-dimethylaminopropionitrile, catalyst and solvent are added into the autoclave, nitrogen is passed to remove air, hydrogen is passed at an appropriate temperature, the kettle pressure is 5MPa, until the kettle pressure does not drop as the end point, cooling, desolubilizing under reduced pressure, collecting 73~75 ℃/9 × 103Pa fraction to obtain N,N-dimethyl -1, 3-dipropylamine. Finally, the upper product is mixed with solvent and acid binding agent in a three-mouth bottle, n-propyl chloroformate is added dropwise under cooling, the reaction temperature is 30~40 ℃, the reaction is continued for 1h after dropping, filtering, washing, collecting filtrate and washing liquid are desolated under reduced pressure to obtain downamocarb product. The yield is 66% ~ 67%, and the content is more than 90%. |
