Molecular weight distribution analysis of wood pulp cellulose by size exclusion chromatography

Creator:

Silva, Arlene Avenido

Abstract:

Automated size exclusion chromatography with a differential refractometer detector was employed to study the molecular weight distribution patterns in various types of wood pulp cellulose. The results obtained were correlated with the conventional methods of measuring these properties. The dissolution of pulp celluloses in N,N-dimethylacetamide-lithium chloride solvent was optimized.
