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.

Synthetic method of s-metolachlor

The invention belongs to the field of herbicides and particularly relates to a synthetic method of s-metolachlor. The synthetic method of s-metolachlor comprises the steps that a cheap compound 2-methyl-6 ethyl benzene easy to obtain is used as a raw material, and finally the high-quality herbicide product s-metolachlor is obtained through condensation reaction, catalytic hydrogenation reduction reaction, chloride acetylation reaction and purification treatment. The simple water-phase s-metolachlor synthesis method easy to execute is provided, the yield of the s-metolachlor product reaches 98.5% and the purity reaches 98.2% in a kilogram-level experiment, and the environment-friendly synthesis method is suitable for industrial production. In addition, compared with a traditional organic solvent synthesis method, use of organic alkali is avoided, few post-treatment steps are adopted, the production pollution is low, the cost is low, required material types are few, the solvent use amount is small, the cost is low, and the method is suitable for large-scale popularization and use.
