Abstract:Carboxymethyl chitosan with a degree of substitution > 0.8 was synthesized under optimum reaction condition.The product was analyzed with IR and H-NMR.The effects of degree of substitution,synthesis temperature,concentration of Ca2+ and scaling inhibition,at constant temperature,time and pH of solution on the scale inhibition performances of the carboxymethyl chitosan was studied.The results indicate that carboxymethyl chitosan has better Ca2+ inhibition performance with inhibiting rate > 91%.
Keywords:carboxymethyl chitosan  scaling inhibitor in sugar industry  inhibiting rate  substitutive degree
