The invention relates to the technical field of
creatine monohydrate preparation, and discloses a
creatine monohydrate synthesis preparation method and equipment, and the method comprises the following steps: S1, adding
chloroacetic acid and
methylamine water into a reaction kettle, and carrying out a reaction at 20-30 DEG C for 8-10 h; s2, the temperature is raised to 80-95 DEG C, the
heating time is 1-3 h, and unreacted
methylamine is recovered; s3, adding a
sodium hydroxide solution into the solution obtained in S2, and neutralizing reaction by-products; s4, heating to 105-110 DEG C, and concentrating under reduced pressure to obtain a
sarcosine aqueous solution; s5, filtering the
sarcosine aqueous solution in the step S4, and taking filtrate into a crystallizer; s6, continuously introducing
ammonia gas into the crystallizer, stirring, adjusting the pH value of the solution to 9-12, and then performing
crystallization treatment on the reaction solution to obtain
creatine crystals; and S7, filtering, washing and
drying the creatine crystals in the step S6 to obtain crude
creatine monohydrate. The method has the following advantages and effects that the reaction efficiency and the conversion rate are relatively high, the produced
creatine monohydrate is high in purity and stable in quality, and the requirements of different fields on the product quality can be met.
