This article discusses comparative investigation of etherification reaction kinetics of cotton andmicrocrystalline cellulose, in heterogeneous conditions by solid-phase method in the special adiabatic reactor. On the basis of the received results, activation energy, constant of reaction rate, pre-exponential factors and specific thermal effects of carboxymethyllation reactions of cotton and microcrystalline cellulose were determined.
