The new cellulose derivative containing nitrogen “Propionic Acid Hydrazide-3-(OCellulose)” was prepared from bleached kraft bagasse pulp via the formation of methyl propionate-3-(OCellulose), [MPC]. Different reaction variables were applied during the formation of [MPC], such as : sodium hydroxide concentration, sodium hydroxide to cellulose ratio, time and temperature of reaction. On the basis of the results from IR-absorption spectra the optimum conditions of the formation of [MPC] by Michael addition reaction were determined. The prepared Propionic Acid-Hydrazide-3-(OCellulose); [PAHC], and its combination with some metal ions were characterized by FTIR-spectra, micro-analyses and thermal analysis. The thermal properties were evaluated by non-isothermal TGA and the activation energies of the degradation of the samples were calculated using the Coats and Redfern equation. |
