| Physical and Chemical Properties | Chemical water is a yellowish brown transparent oily liquid. B. p.202 ℃/1.33 × 103Pa, vapor pressure 7.466 × 10-1Pa (25 ℃), relative density 1.065, refractive index n20D1.5124. Soluble in acetone, methanol, isopropanol, benzene, xylene, solubility in water 0.8g/L (20 ℃). The half-life of pater field is 21 ~ 25d, and ammonia and carbon dioxide are decomposed by soil microorganisms. It is stable and non-corrosive to heat, but it is not suitable to use PVC pipes or containers when using drugs. |
| Use | Uses Cedar is the main herbicide for direct seeding rice. Its herbicidal effect is due to the transformation of Yinzhi protein, so that the proliferating cells cannot get protoplasm, and only the empty cells in the cell wall make the new leaves unable to grow, and the growth point is twisted., Eventually burst and die. It is used to control barnyard grass in paddy fields and has special effects on barnyard grass. |

Toxicity
the acute oral LD50 of male rats is 501~720 mg/kg (the original drug is 468~705 mg/kg), and the acute oral LD50 of mice is 795 mg/kg; The acute percutaneous LD50 of rats is> 1200mg/kg, and the acute percutaneous LD50 of rabbits is> 4600mg/kg. Rats and dogs were fed at 8 mg/kg and 30 mg/kg per day for 3 months respectively, and no poisoning symptoms were found. The 2-year feeding test-free dose was 0.63 mg/kg per day for rats and 7.2 mg/kg per day for mice. Toxic to fish, goldfish LC50 is 30mg/L (96h), rainbow trout LC50 is 0.2mg/L (96h). It is harmless to birds, natural enemies and bees. It has a stimulating effect on the eyes and skin.
Production method
There are phosgene method and oxygen carbon sulfide method. 1. The phosgene method reacts the gas with hexamethyleneimine to form hexamethyleneformyl chloride, which is then obtained by mercaptylation with ethanethiol in the presence of excess base. It can also be obtained by reacting phosgene with ethanethiol to form S-ethyl thiochloroformate, and then reacting with hexamethylene imine. 2. Carbon oxygen sulfide method Carbon oxygen sulfide reacts with hexamethylene imine under the action of alkali to generate sodium N,N-hexamethylene carbamate, which is then obtained by reacting with diethyl sulfate or other ethylating agents.
