摘要：
Ionic liquids (IL) based on 1-alkyl-3-methylpyridinium and cellulose solutions in them were studied experimentally using PMR. It was shown that the chemical shifts for H2 and H6 of the pyridine ring changed most upon changing the length of the alkyl substituent in the IL cation and in the cellulose solutions. The experimental results could be useful for explaining the interaction mechanism between natural polymers and IL.
