| titleOfInvention | The preparation method of high-purity ethyl demethylaminothiazolyloximate |
| abstract | The invention belongs to medical synthesis technical fields, are specifically related to a kind of preparation method of high-purity ethyl demethylaminothiazolyloximate.Mixed solvent, insulated and stirred after heating are added into ethyl demethylaminothiazolyloximate crude product；Hydrochloric acid regulation system pH is added, after system dissolved clarification, active carbon is added and reducing agent is stirred；Be filtered to remove active carbon, filtrate with organic base regulation system pH in 4.5-6.5, then insulation reaction；Cooling rejection filter obtains ethyl demethylaminothiazolyloximate fine work.The preparation method of high-purity ethyl demethylaminothiazolyloximate of the present invention, simple process effectively raise the purity of ethyl demethylaminothiazolyloximate, and purity optimizes product quality 99.85% or more, at low cost, high income, are suitble to industrialized production. |
