Application | 5-aminopentanoic acid hydrochloride as a bio-derived chemical can be used to synthesize valerolactam of nylon 5. In addition, as a C5 platform compound, 5-aminopentanoic acid can also be used to synthesize Glutaric acid, pentanediol, 5-pentanoic acid, etc. |
Use | 5-aminovaleric acid is a typical terminal amino acid, it can be used to produce novel odd-numbered nylons, such as nylon -5, nylon -6,5 and nylon -5,5. In addition, 5-aminopentanoic acid is also an important C5 platform compound, which can be used in the synthesis of important compounds such as Glutaric acid, 1, 5-pentanediol and 5-hydroxyvaleric acid. |
preparation | There are three main biosynthetic pathways of 5-aminopentanoic acid: enzyme-catalyzed pathway, whole-cell catalytic pathway and fermentation pathway. The conversion solution of 5-aminopentanoic acid obtained by enzyme catalysis is NH4HCO3 solution with pH 7.8, and the conversion solution also contains a small amount of substrate lysine and product 5-aminopentanoic acid; the 5-aminopentanoic acid conversion solution obtained by whole cell catalysis contains about 14g/L phosphate buffer solution, about 2g/L sulfate, and a small amount of lysine and glucose; the fermentation broth of 5-aminopentanoic acid obtained by fermentation contains about 10g/L of phosphate, about 16g/L of sulfate, and a small amount of residual glucose and lysine, separation of 5-aminopentanoic acid by ion exchange resin, the method to filter bacteria through flocculation, macroporous adsorption resin decolorization, and finally by ion exchange resin separation of 5-aminopentanoic acid. |
