Preparation of Small Molecular Hemicelluloses from Coconut Shell

Abstract:

A kind of small molecular hemicellulose was prepared from coconut shell by ultrasound-assisted and alkaline hydrogen peroxide extraction. Unlike the common hemicelluloses and celluloses, it is similar to liquid for the hemicelluloses in ethanol solution, but insoluble in it. Through the gel permeation chromatography (GPC) analysis, it was found that its molecular weight is much lower than that of the traditional hemicelluloses, indicting the lower polymerization degree. But from the infrared spectroscopy spectra analysis, this type of small molecular hemicelluloses has the similar infrared spectrum characteristic peaks to that hemicellulose.
