Acceleration of the xanthation process of alkali cellulose

Abstract

In spite of the abundance of articles and monographs devoted to the xanthation of alkali celluose [i, p. 243; 2, p. 86; 3, p. 157], up untilnowit has not been clear whether it is advisable to carry out this process at an elevated or reduced temperature, with vigorous or only slight agitation, or in the absence ("dry" method) or presence of solvent alkali ("wet" method). Moreover, the xanthation process of alkali cellulose is complicated by reactions involving the formation of by-products. Therefore the xanthation reaction cannot be described by simply kinetic equations of the first or second order, and is described only by complex equations for parallel and consecutive reactions.
