Abstract

Dimethylformamide applied at 100°C. and at the boil to ethylenediamine–cellulose complexes decomposed the complexes, giving products whose x‐ray diffractograms are almost identical with that of cellulose IV prepared by means of glycerol at 250°C. The product derived from cellulose II has a 002 interplanar spacing of 4.04 A., those from cellulose I and III have a spacing of 3.98. The 101 and 101 interplanar spacings are the same for all the products, 5.71 A. The infrared spectra of the products are markedly similar to those of the original cellulosic starting materials, except in the case of cellulose III. This modification has a cellulose II type of infrared spectrum; that of the product is markedly similar to the infrared spectrum of cellulose I. Application of sodium hydroxide solution and of ethylenediamine to the decomposition products of the complexes produced cellulose II and the ethylenediamine‐cellulose complexes, respectively. Anhydrous ethylamine failed to produce cellulose III.
