METHOD FOR PREPARING VERY LOW VISCOSITY CELLULOSE ETHER AND PRODUCT. |
摘要 |
<p>The present disclosure is directed to methods for producing a very low viscosity cellulose ether having little or no discoloration and cellulose ether products resulting therefrom. The method includes contacting a cellulose ether with an oxidizing agent and an acid to form a mixture. The mixture is then heated and neutralized. The method includes adding a second oxidizing agent to the mixture and forming a very low viscosity cellulose ether having a viscosity from 1.2 cP to less than 2 cP. The very low viscosity ether may also have an APHA color value of 1 to 100.</p> |
