Abstract
The last stages of the reaction between a hydrocellulose and the Braidy copper-number reagent are extremely slow. The cellulosic residue from the conventional copper-number determination still possesses appreciable reducing power, and the elimination of the reducing power may require as many as seven successive treatments with the copper-number reagent under the standard conditions. The reactions involved lead to the production of carboxyl groups, and about 22 atoms of copper are reduced per carboxyl group formed. The theoretical implications of these observations are discussed.Keywords
