| Abstract: | A new quaternary alkyl ammonium starch ether (M-YJJ) was synthesized from dodecyl dimethyl epoxypropyt ammonium chloride and starch by semidry-semiwet method.The optimal synthetic conditions were found as follows:dosages of dodecyl dimethyl epoxypropyl ammonium chloride, starch ethyl alcohol and NaOH are 7.2 g, 5.5 g, 5 -6 mL and 0.13 g, respectively, w(H_2O)=20%-30%, reaction temperature 80℃, reaction time 2.5 h. The cationic degree of M-YJJ is 36.6%. |
