| toxicity | acute oral LD50>8000mg/kg in rats and mice,> 4000mg/kg in dogs and guinea pigs, and> 4000mg/kg in rats. Rats were fed at doses of 250mg/kg and 500mg/kg per day for 4 months and all survived, but their food intake decreased. The concentration of acute inhalation in rats was 1mg/L. Slight irritation to skin and eyes. No teratogenic, carcinogenic and mutagenic effects were found in animal experiments. The non-effective dose of rats in the third generation reproduction test was 25 mg/kg per day, and the delayed neurotoxicity test was not abnormal. The non-effective dose of rats in the 2-year feeding test was 5~10 mg/kg per day, and carp LC5050mg/L. Quail LD502900mg/kg. |
| use | post-bud herbicide in sugar beet field to control weeds such as chickweed, white mustard and quinoa, and apply pesticide at 2-4 leaf stage with an dosage of 5-15g active ingredient/100 m2. This product is a post-bud herbicide for beet fields. It is suitable for controlling broad-leaved weeds in sugar beet fields, such as chickweed, quinoa, mustard, wild oats, wild sesame, wild radish, shepherd's purse, cow tongue, ferret flower, cow vine chrysanthemum, etc. Beet Ning is a post-bud herbicide in sugar beet fields. |
| production method | there are two synthetic ways. (1) The reaction of m-aminophenol and methyl chloroformate in acetonitrile is first prepared into 3-methoxycarbonylaminophenol, and then reacted with m-toluene isocyanate to prepare beet ning. (2) The 3-methoxycarbonylaminophenol obtained by the above method reacts with phosgene in the presence of dimethylaniline to produce chloroformic acid (3-methoxycarbonylaminophenyl) ester, and then with m-methylaniline in the presence of sodium carbonate Condensation reaction to obtain beet ning. Preparation method 1: The reaction of methyl chloroformate and m-aminophenol in acetonitrile solvent is first prepared into 3-methoxycarbonylaminophenol, and then reacted with m-toluene isocyanate to synthesize beet ning. Preparation method 2 Reacts 3-methoxycarbonylaminophenol with phosgene in the presence of dimethylaniline to form chloroformic acid (3-methoxycarbonylaminophenyl) ester, which is then deposited in sodium carbonate and m-methylaniline Condensation to prepare beet ning. |
