| Abstract: | A way for synthesis of zwitterionic guar gum containing sulfobetaine from epichlorohydrin,sodium bisulfite,dimethylamine and guar gum was designed.IR was used to characterize the sulfobetaine zwitterionic intermediate compound and zwitterionic guar gum containing sulfobetaine.The effects of reaction temperature,reaction time and the dosages of NaOH and etherifying agent on the substituting degree were investigated and the optimal conditions were determined as follows: reaction temperature of 70℃,time of 5 hours,mass ratio of NaOH to guar gum of 0.09 and mass ratio of etherifying agent to guar gum of 0.5. |
