INVESTIGATIONS INTO CELLULOSE AND RELATED SUBSTANCES. THE CONSTITUTION OF METHOCEL.
Abstract
Methocel (a partially methylated cellulose derivative) was fractionated by precipitation with thymol, and the various fractions were subjected to periodate oxidation. The resulting dihalides were then hydrolyzed with H2S04. The findings indicate that only certain glucose units are affected by the methylating reagents and that they are probably located in the same general region of the cellulose molecular complex. The areas of the molecular complex attacked by periodate appear to be those unaffected by the methylating reagent. It is concluded that the above areas correspond to the crystalline regions of the complex.
