| titleOfInvention | A kind of purification process of mibemycin oxime crude product |
| abstract | The present invention relates to a kind of purification process of mibemycin oxime crude product, its processing step is：Mibemycin oxime crude product is washed under the conditions of pH 89 first, then the mibemycin oxime wet product obtained by filtering is dissolved in butyl acetate or isobutyl acetate, again through macroreticular resin decolorization, water is added to mix, stratification simultaneously filters, and gained filtrate is dried with anhydrous calcium chloride, filtering and collecting filter liquid, again plus water mixing, heating crystallization and filtration, drying can obtain mibemycin oxime sterling.The present invention is realized in mibemycin oxime crude product and efficiently separated impurity, improves final product quality, is advantageous to strengthen the domestic and international market competitiveness of product. |
