| Abstract: | A method is suggested for the determination of carbonyl groups in cellulose based on the reaction with hydrazine. After washing with water, the cellulose hydrazone is dissolved in sulfuric acid and hydrolyzed. The liberated hydrazine is determined colorimetrically with p-dimethylamino-benzaldehyde. Possible interferences from carboxyl groups are discussed. |
