Purifying device of amino acid

Abstract

The invention discloses a purifying device of an amino acid. The purifying device comprises a primary purifying section, a pre-purifying section, a post-purifying section and a collecting section, wherein an amino acid mother liquid is firstly subjected to separation and purification through the primary purifying section, and is subjected to online monitoring through a primary liquid chromatograph; high-concentration amino acid liquid of which the amino acid mass fraction is higher than 99.0% is directly introduced into the collecting section to collect; the residual primary amino acid liquid is introduced into the pre-purifying section to be purified again; the effluent primary inorganic salt is introduced into the post-purifying section to be purified again, the mixed amino acid is separated out, and finally the separated liquid is collected. According to the purifying device, the amino acid mother liquid can be separated and purified; the concentration of the amino acid in the purified amino acid liquid is higher than 99.0%; and the amino acid is thoroughly separated from the inorganic salt.

Description

technical field [0001] The invention relates to the technical field of organic chemical synthesis and separation, in particular to a purification device for extracting amino acids from amino acid mother liquor. Background technique [0002] Amino acid is a general term for a class of organic compounds containing amino and carboxyl groups. Amino acid is the basic unit of protein, which endows protein with a specific molecular structure and makes its molecules biochemically active. Protein is an important active molecule in organisms, including enzymes that embrittle metabolism. In nature, there are more than 300 kinds of amino acids. [0003] ?Amino acids are mainly used in medicine to prepare compound amino acid infusions, and are also used as therapeutic drugs and synthetic peptide drugs. At present, there are more than 100 kinds of amino acids used as medicines, including 20 kinds of amino acids that make up proteins and more than 100 kinds of amino acids that make up no...

AI Technical Summary

Problems solved by technology

In many production processes, inorganic salts may usually be contained in amino acid mother liquor, and conventional processes are often purified by concentration or solvent, due to (NH4) 2 SO 3 , (NH4) 2 SO 4 、Na 2 SO 3 with Na 2 SO 4 It is very easy to bond, and the separation of amino acids and inorganic salts is difficult to achieve the desired effect. The whole process directly affects the yield, so the production cost is high, the energy consumption is large, and the labor intensity is high.
