| titleOfInvention | A kind of method of purifying cm-chitosan |
| abstract | The invention discloses a kind of method of purifying cm-chitosan, be specially when purifying cm-chitosan, the pH when pH of solution being reduced to cm-chitosan iso-electric point, obtain concentrated cm-chitosan, and/or concentrate cm-chitosan with the water washing that pH is identical with pH during iso-electric point and remove salinity in concentrated cm-chitosan, obtain the cm-chitosan that desalts; Finally carry out repetitive scrubbing with high concentration ethanol to the cm-chitosan that desalts to make it to separate out acquisition high purity cm-chitosan, it is the improvement to the method for purifying cm-chitosan in prior art.In the present invention, purification process saves the consumption of ethanol greatly, obtain the cm-chitosan that purity is greater than 99%, and reduce cm-chitosan salinity, especially the large Chemical Manufacture of high molecular cm-chitosan is applicable to, and the application making the final cm-chitosan obtained be more suitable at cosmetic field. |
