反応手順
Cellulose (20 g), sodium hydroxide (10 g), water (30 g), and ethanol (150 g) are charged into a 500 ml glass reactor. The resulting alkali cellulose is stirred 45 minutes at 25° C. Then monochloroacetic acid (15 g) and hexylchoride (1 g) are added and the temperature raised over time to 95° C. and held at 95° C. for 150 minutes. The reaction is cooled to 70° C., and then cooled to 25° C. Neutralization is accomplished by the addition of a sufficient amount of nitric acid/acetic acid to achieve a slurry pH of between 8 and 9. The slurry is filtered to obtain a hexylether of CMC.
