Preparation of trichlorochrysanthemic acid [Method 1]
The preparation method comprises the following steps: adding metered sodium hydroxide solution and solvent into a reaction kettle, stirring, adding cis-trans -3- (2,2-dichloro-3,3,3-trifluoropropane)-2,2-dimethyl cyclopropane carboxylic acid methyl ester, heating to reflux temperature until the reaction is complete, and taking about 6 hours; recovering the solvent; adding hydrochloric acid to adjust pH value; and moving into the reactor.
