文摘The cationic starch was prepared via reaction of starch with N (2,3 glycidyl)trimethyl ammonium chloride(GTA) using fatty alcohol polyoxyethylene ether(FAPE) as a catalyst in dry process . The effects of the catalyst, reaction time, reaction temperature, amounts of FAPE and sodium hydroxide on the reaction efficiency were discussed.
