Preparation method of pyridoxal 5-phosphate monohydrate

The invention provides a preparation method of pyridoxal 5-phosphate monohydrate. The preparation method comprises the following steps: 1, first oxidizing pyridoxine hydrochloride to pyridoxal hydrochloride, adding sodium sulfide, then dropwise adding p-ethoxyaniline to the solution, and carrying out a reaction to produce a pyridoxal hydrochloride Schiff base; 2, adding polyphosphoric acid to thepyridoxal hydrochloride Schiff base, performing a stirring reaction, first hydrolyzing polyphosphoric acid and then performing neutralization with an alkali solution to precipitate a large amount of an orange-red solid after the reaction is completed, and filtering and washing the solid to obtain a pyridoxal 5-phosphate Schiff base; and 3, hydrolyzing the pyridoxal 5-phosphate Schiff base with a 2mol/L of alkali solution, adding an organic solvent for extracting and performing liquid separation, adding a strong acid cation exchange resin into the aqueous phase, performing stirring for 1.0 h and then performing vacuum filtration, and performing freeze drying on the filtrate to obtain pyridoxal 5-phosphate monohydrate. The preparation method of pyridoxal 5-phosphate monohydrate is simple inoperation, mild in reaction conditions, relatively high in purity and yield of the final product, and suitable for industrial application, and has relatively good economic benefits.
