Technical solution for enzymatic production of nylon 56
Nylon 56, a new type of bio-based nylon products, has the advantages of excellent skin-affinity, high strength, and good hygroscopicity as a fabric. From lysine extract, we produce high-quality nylon 56 salt through biocatalytic reaction, salt-forming reaction, purification and crystallization, and then polymerize to produce nylon 56.
In the design of technology route, we make full use of mature resin purification technology of lysine production technology. In the premise of ensuring the cost of raw materials, the impurities of lysine raw materials are removed as far as possible, thus reducing the difficulty of purification in the post-process. The high quality of nylon 56 salt is ensured by modern crystallization technology. Finally, the polymerization is achieved. There is no inflammable and explosive link in the whole process, so the technology is safe, reliable and investment-saving.
