T
he coconut fiber is a lignocellulosic waste found in abundance; however, it is normally not reused even though, it is an important
cellulose source. In this context, within the possible applications of cellulose that comes from this waste are: bioethanol, composites
and biodegradable plastics, such as cellulose acetate.Therefore, knowing the importance of the application of this material in processes,
the objective of the work is to purify the coir fiber and cellulose fiber with the aim of producing cellulose acetate. The process was
initiated with the fiber’s milling, followed by pulping and whitening that together resulted in a delignification of 66.37%. This also
accomplished the synthesis and characterization of the ionic liquid n-butylammonium acetate that was proved to be the right one by
nuclear magnetic resonance analysis. With the ionic liquid, the treatment of coir fiber followed by whitening was fulfilled resulting in
a delignification of 0.82 and 6.10% respectively. After this, the esterification was accomplished generating cellulose triacetate that was
characterized by Infrared Spectroscopy, Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD) and Degree of Substitution.
These methods gave related results, because the surface crystallinity and characteristic bands are similar in the triacetates produced
by all the three materials. This means that when producing cellulose triacetate, the delignification treatment is not needed.
