OPTICAL ROTATORY DISPERSION OF WATER-SOLUBLE CELLULOSE DERIVATIVES

摘要

Optical activity characterizing features of the spatial structure of simple molecules was known even during the last century from the work of J. Biot, L. Pasteur, J. H. Van't-Hoff, A. M. Butlerov, and others. It is also known that features of the spatial structure of molecules determine various properties of a substance and play a major role in processes of synthesis, This question has been little studied as applied to cellulose and its derivatives. In the dissertation [1], which gathers together practically all the material on the optical activity of cellulose and cellulose acetate, there is no information on the connection of optical activity with the conditions of synthesis, the properties of the polymer, and the quality of the products. There are no clear ideas on the role of the functional groups of cellulose esters in the optical activities of their solutions.
