| Abstract: | Using refined cotton, chloroacetic acid, sodium hydroxide and hydrogen peroxide as main feedstock, sodium carboxymethyl cellulose was made by the process of basification, etherification, abstersion and drying. Meanwhile adopting two-step process of viscosity-decreasing method, i.e. adding hydrogen peroxide during the process of basification and abstersion to decrease the viscosity of alkaline cellulose, as a result the sodium carboxymethyl cellulose with ultra low viscosity was obtained. |
