Abstract
The dissolution of cellulose in CuII–amine solvents, and the subsequent gelation of these solutions with concentrated NaOH solution, have been studied with ESR and optical absorption spectroscopies. A CuII–cellulose complex has been characterised in homogeneous CuII–cellulose gels. This species is similar to that formed when CuII is adsorbed on fibrous cellulose under alkaline conditions. A second complex is postulated, formed on initial dissolution of cellulose in CuII–amine solvents, prior to complete gelation with base.This publication has 14 references indexed in Scilit:
