Abstract:Taking wheat starch of Guanzhong in Shaanxi as raw material to prepared sodium carboxymethyl starch used wheat starch, the effects of raw material ratio, reaction temperature and reaction time during the production with ethanol solvent method were studied. The best conditions were that the ratio of starch : chloroacetic acid : NaOH was 1 : 0.36 : 0.21, 85% ethanols concentration, 50℃, and 2.0 h.
Keywords:wheat starch  sodium carboxymethyl starch  etherification  viscosity
