Separation method of clindamycin phosphate and product thereof

The invention provides a separation method of clindamycin phosphate and a product thereof, and belongs to the technical field of clindamycin phosphate. Comprising the following steps: (1) adding alkaline water into clindamycin phosphate reaction hydrolysate, adjusting the pH value of a system, adding a precipitation reagent, reacting to generate a precipitate, and filtering to obtain a clindamycin phosphate precipitate; (2) adding the clindamycin phosphate precipitate into water and ethanol, stirring and heating, adding concentrated hydrochloric acid until the precipitate is completely dissolved, controlling the pH value of the system to be 3.5-4.5, adding activated carbon for decoloration, and filtering out the activated carbon and insoluble impurities while the solution is hot to obtain a decolorized solution; and (3) adding ethanol into the decolored solution, stirring, cooling, crystallizing, filtering and drying to obtain clindamycin phosphate. The preparation process is simple to operate and low in ener
