TEMPO-Mediated Oxidation of Unbleached Bagasse Pulp

Abstract:

In the paper, unbleached bagasse pulp was oxidized with sodium hypochlorite with catalytic amounts of 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO) and sodium bromide in water. After the TEMPO-mediated oxidation, the oxidized pulp were collected and characterized in terms of morphology, water retention values, crystallinity and deposition properties. The signiﬁcant changes in morphology were observed before and after the oxidation. Crystallinity of cellulose I was nearly unchanged during the oxidation. Water retention value of pulp can be increased from 68.9% to 70.7% by the TEMPO-mediated oxidation. The TEMPO- oxidized pulp was homogeneously dispersed in water when the pulp consistency is 0.1%.
