Water flux through cellulose triacetate films produced from heterogeneous acetylation of sugar cane bagasse

摘要

In the present study the reaction of heterogeneous acetylation was applied to sugar cane bagasse. The product of heterogeneous acetylation was characterized using: (a) Fourier transformed infrared (FT-IR) spectroscopy based on the presence of the C=O stretch band of the carbonyl group (around 1740 cm~(-1)), (b) wide angle X-ray scattering (WAXS) based on the presence of a maximum in the region of 2θ between 5 and 10, and (c) differential scanning calorimetry (DSC) based on the presence of an endothermic peak at approximately 300 deg C.
