摘  要:
Carboxymethyl corn powder has been prepared from corn powder by carboxymethylation. The effects on viscosity of production of ethanol concentration, sodium hydroxide concentration, reaction time and reaction temperature were studied. The optimum reaction condition was that the ratio of the raw materials, corn powder, sodium hydroxide, chloroacetic acid=8.1∶3.5∶4.8, the temperature was 50?℃, the time was 4?h. The viscosity of production reaches 650?mPa·s in 2.5% water solution at 25?℃.
