| Abstract: | In this work, cellulose from beans straw was used to produce a more hydrophobic material (cellulose acetate) for use as oil absorbent. Acetic anhydride was used in the reactions with two catalysts, pyridine (PY) and N-bromosuccinimide (NBS). The materials produced were characterized by infrared spectroscopy, scanning electron microscopy, X-ray diffraction and elemental analysis. NBS proved more efficient than PY, with the resulting materials containing higher number of acetate groups, being more hydrophobic and with higher capacity to absorb soybean oil. |
