Method for preparing 3 - amino -2, 4 -dimethylthiophene (by machine translation)

The invention relates to the field, and relates to the field of chloroacetamide preparation. The invention discloses a preparation method, namely 3 -) and -2 dimethylamino 4 - and the method comprises the following steps, 1) cyclization decarboxylation 2, 5 -dimethyl -3 -thiobenzoic acid, 2, 4 -dimethyl tetrahydrothiophene -3 - ketone; 2) rearrangement to obtain 2 amino 4 -3 -dimethylthiophene after condensation with hydroxylamine or a salt thereof in the presence of an acid 3 - anhydride -2 and 4 - a base in the presence of an acid anhydride and a base. By the method, the yield is high, and the yield is high. The preparation method of-amino,dimethylthiophene is suitable for large-scale production. 3 -2 4 . (by machine translation)

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.

NOXIOUS ARTHROPOD CONTROL AGENT CONTAINING AMIDE COMPOUND
