Abstract: Ultraviolet absorption spectra for cadoxene solutions of benzoyl-, 2-furoyl-, 2-furoylacetyl-, 3-(2-furyl)acryloyl-, 3,5-dinitrobenzoylcellulose, methyl 2,3,4,6-tetra-0-(2-furoyl)-a-D-glucopyranoside, and octa-0-(2-furoyl)cellobiose have been measured. The obtained spectral data were satisfactorily used in the determination of the degree of substitution of the substrates. The chemical changes during the process of dissolution of cellulose esters in cadoxene have been studied.
