Abstract
The interaction of nitro-H-carboxymethylcellulose with a solution of sodium hydroxide has been investigated. Three reactions take place in parallel: neutralization of the −COOH groups, denitration, and degradation of the main chain at the β-glucosidic bonds. Conditions permitting these reactions to be regulated have been found. It has been established that when not less than 80 mole-% of −COONa groups and not more than 130 mole-% of −ONO2 groups are present the product of the neutralization reaction (nitro-Na-CMC) is soluble in water.
