Acetylation bagasse

More recently, fiberboards have been made from acetylated bagasse fiber [58] and acetylated aspen fiber [59,60]. The fiberboards swelled at a much slower rate and to a lesser extent than control fiberboards [58], and their internal bond strength [58] and biological resistance [59] were greater. [Pg.167]

Abdel-Hadi and Helmy [15] prepared Cr(III] complexes using acetylated bagasse dissolving pulp (I] and acetylated bagasse kraft paper pulp (II] as ligands. These complexes were also characterized by means of electronic and vibrational data. The electronic absorption spectra of Cr III with I and II exhibit absorption bands at 16,666 and... [Pg.270]

Acetyl, benzoyl, lauryl, 4-phenylbutyryl, phenoxyacetyl, and other esters of cellulose have been prepared. Investigation of these esters as hydrophobic materials for immobilizing enzymes showed that the phenoxyacetyl derivative is the most versatile. A procedure for acetylating bagasse cellulose has been reported. ... [Pg.457]

Repeated methylation of bagasse native lignin with dimethyl sulfate yielded a product with a 29-1 % methoxyl content. Four such methyl-ations did not change this value. However, the infrared spectrum of this derivative still revealed a small absorption band at 3400 cm1. Thus, it appeared that at least one hydroxyl group could not be methylated. Treatment of this methylated product with acetic anhydride and pyridine gave an acetate, which did not exhibit an absorption band at 3400 cm-1. Consequently, a tertiary hydroxyl group, which can be acetylated but not methylated, seems to be present in this lignin. [Pg.84]
