| titleOfInvention | High-purity selective preparation and purification method of aminothiazoly loximate dimer |
| abstract | The invention discloses a high-purity selective preparation and purification method of an aminothiazoly loximate dimer, which comprises the following steps: A. adding aminothiazoly loximate and organic base into a low-boiling-point solvent, and stirring to dissolve the mixture; B. preparing mixed anhydride; C. selective condensation: adding the aminothiazoly loximate acid solution obtained in the step A into the mixed anhydride solution system obtained in the step B, adding a catalyst, reducing the generation of trans-aminothiazoly loximate dimer through the control of process conditions, and realizing the selective condensation to prepare high-purity aminothiazoly loximate dimer; D. and (5) purifying the product. The method for preparing and purifying the aminothiazoly loximate dimer greatly reduces the generation of trans-isomer through selective condensation reaction, and obviously improves the product yield and purity. |
