Abstract

Comparative study of reaction activity of cotton cellulose, microcrystalline cellulose and nanocellulose during periodate oxidation and carboxymethylation were investigated. The functional composition of this cellulose samples were studied and determined the number of formed functional groups in the hydrolysis products. It was found that increase of reaction activities among cotton cellulose-microcrystalline cellulose-nano cellulose depend on quantity of formed functional groups and their high surface area in the same sequences. Also investigated carboxymethylation reaction kinetics of cotton, microcrystalline and nanocellulose and determined the activation energy for etherification process.

Keywords

Cellulose, Microcrystalline Cellulose, Nanocellulose, Oxidation, Carboxymethylation, Kinetics, Reactivity.

Abstract

At the end of 80-years of the last century into scientific terminology introduce a family of new terms with prefix «nano» as: nanotechnology, nanostructure, nanocompocitematerial, nanocluster, nanochemistry, nanophysics, nanobiotechnology and etc. In all over countries there were editions, journals where published results devoted exclusively to nanomaterials.
