Abstract

This invention relates to process method for cyclodextrin polymer analogue enzyme fiber, which uses cyclodextrin single part polymer to connect analogue enzyme to fiber to process analogue enzyme with certain catalyze function. Comparing with current technique, this invention has the following advantages as: a, this fiber cyclodexitrin is of multiple identification functions; b, knitting and shearing of the function fiber; c, besides this method can resolve recycle use and product isolation by use of polymer as imitation catalyze agent.

Description

technical field [0001] The invention relates to a cyclodextrin and its derivatives, in particular to a preparation method of a cyclodextrin polymer imitating enzyme functional fiber. Background technique [0002] Compared with ordinary chemical catalysts, enzyme catalysis has the advantages of high efficiency, specificity and mild reaction conditions, but natural enzymes are too sensitive to the environment, require harsh operating conditions, are easily inactivated, and are expensive. People try to inherit the advantages of enzymes , to change the shortcoming of its variability and inactivation, and start the simulation study of enzyme function. Such enzyme model molecules currently used to construct simulated enzymes include cyclodextrin, crown ether, cryptin, cage ether, porphyrin, etc. Cyclodextrin is an ideal enzyme model. The characteristic of cyclodextrin catalysis is that the substrate molecules participating in the reaction are first encapsulated by cyclodextrin mo...
