The acetone is evaporated until the crystals are separated out, and the obtained product is obtained by suction filtration. Cantharidin high-quality goods, slowly drip into sodium hydroxide solution, after the reaction is complete, add medicinal charcoal aqueous solution, and suction filter while it is hot to obtain sodium cantharidate solution, then dry it, and actually make sodium cantharidate fine powder The purity is high, and the effect of dissolving in water is better, so that the utilization rate of resources in the process of use is higher, and the bioabsorption rate also increases accordingly. The preparation method uses exquisite materials, and the actual production capacity is outstanding. Chemical recovery rate.

Method for preparing active pharmaceutical ingredient of magnesium aspartate hydrochloride
InactiveCN106916075ASimple processSuitable for industrial productionOrganic compound preparationAmino-carboxyl compound preparationCentrifugationFiltration
The invention discloses a method for preparing an active pharmaceutical ingredient of magnesium aspartate hydrochloride. The method comprises the following specific steps: (a) adding a formula specified volume of purified water into a solution preparation tank, carrying out heating, adding weighed magnesium oxide into the tank with stirring, adding aspartic acid into the tank in batches with stirring, and continuing to stir until the solution is clarified after adding is completed; (b) carrying out suction filtration on the reaction solution while the reaction solution is hot, carrying out depressurized concentration on filtrate so as to remove 1 / 3 to 1 / 2 of water, naturally cooling remaining liquid to room temperature so as to precipitate a large amount of white solids, and carrying out centrifugation; (c) carrying out drying, so as to obtain magnesium aspartate solids; (d) adding a specified amount magnesium aspartate and a specified volume of water into a reactor, carrying out heating with the temperature of 40 DEG C, carrying out stirring for 20 minutes, adding a hydrochloric solution into the reactor in batches, and continuing to stir until the reaction solution is clarified; (e) adding medicinal charcoal (0.1% W / V), and carrying out stirring with heating; (f) filtering medicated liquid through a decarbonization filter and a 0.45-microgram filter; and (g) carrying out spray drying, carrying out discharging, carrying out crushing, and carrying out subpackaging.
