Usage

Metabolic pathway

14C-Thenylchlor (NSK-850) is degraded in three kinds of paddy soil with a half-life of 1-3 weeks after application. Two major metabolites are identified as N- acetyl and N-hydroxylmethylcarbonyl derivatives which are derived from the replacement of the chlorine atom of thenylchlor by hydrogen and hydroxyl groups, respectively.

Synthesizing method for chloroacetamide compound

The invention discloses a synthesizing method for a chloroacetamide compound. In a reaction kettle, a secondary amine compound is dissolved in an organic solvent, the mixture is heated for reflux, chloroacetyl chloride is added into the mixture, a reflux reaction is conducted for 0.5-20 hours, and the chloroacetamide compound is obtained. According to the synthesizing method for the chloroacetamide compound, an acid binding agent is not used, discharging of wastewater in the after-treatment process is reduced, by keeping the reflux state of the system, hydrogen chloride gas generated from thereaction is exhausted out of the system and absorbed by water outside the system, high-purity hydrochloric acid is obtained, the waste is turned into wealth, the method comes up to the production standard of safety and environment protection, and discharging of waste gas, waste water and waste residues is reduced; according to the synthesizing method for the chloroacetamide compound, few operationsteps are utilized, the reaction speed is high, the product yield is high, the purity is high, the production cost is low, and the method is safe, friendly to the environment and suitable for industrial large-scale production.
