Preparation method of alpha-ketoleucine calcium dihydrate or alpha-ketophenylalanine calcium monohydrate

The invention discloses a preparation method of alpha-ketoleucine calcium dihydrate or alpha-ketophenylalanine calcium monohydrate. In an existing method, the quality of a final product is low, and the content of related substances is high. The method comprises the steps that isobutylidene hydantoin or benzal hydantoin is taken as a raw material and generates a pipeline continuous flow ring-opening reaction with an alcohol-water solution of alkali, and then corresponding alpha-ketoacid salt is obtained, wherein the pipeline continuous flow ring-opening reaction is a continuous ring-opening reaction conducted in a pipeline reactor; the obtained alpha-ketoacid salt is firstly extracted with a hydrocarbon solvent or a halohydrocarbon solvent or a ketone solvent or an ether solvent for impurity removal and then acidized to obtain a corresponding crude alpha-ketonic acid product, the crude alpha-ketonic acid product is extracted with the hydrocarbon solvent or the halohydrocarbon solvent or the ketone solvent or the ether solvent for impurity removal, and then a fine alpha-ketonic acid product is obtained; the obtained alpha-ketonic acid is prepared into calcium salt, crystallization is conducted, and the alpha-ketoacid calcium hydrate is obtained. Accordingly, the high-quality and high-purity alpha-ketoleucine calcium dihydrate and alpha-ketophenylalanine calcium monohydrate are obtained.
