| titleOfInvention | A kind of preparation method of the immobilized cellulose membrane of the beta-schardinger dextrin-for tryptophan chiral separation |
| abstract | The preparation method that the present invention provides a kind of immobilized cellulose membrane of the beta-schardinger dextrin-for tryptophan chiral separation, owing to its molecular structure has itself, the more activity hydroxy that can be used for modifying and cheap and easily-available advantage are chosen as basal lamina material to cellulose membrane.Beta-schardinger dextrin-is chemically bound on the cellulose membrane in 0.22 μm of aperture and prepares chiral separation film.Using dl-tryptophan as splitting object, and characterizing splitting effect, DL-Trp is almost achieved and splits completely by multiple filtration post-modification filter membrane, it is thus achieved that D-trp solution.Chiral film fractionation stability RSD in 12h reaches 3.4%, good stability.Can be widely applied to chemical and medicine industry separation field. |
