cellulose was extracted from abaca fibre which proceed with different alkalization technique, such as with and without heating treatment. The aim of this research is to extract and characterize the cellulose fibre that obtained from abaca fiber as the alternative of textile fibre. The characterization for the cellulose fibre including FT-IR, SEM, and XRD. The FT-IR spectra showed the heating treatment around 70-80°C can separate the lignin and hemicellulose from the abaca fiber. SEM analysis showed the similar result, the heating process during the alkalization treatment able to separate lignin from the cellulose matrix, that was shown with the smoothest surface of cellulose fibre. Crystallinity degree of the obtained cellulose was 65 and 43% for without and with heating process, respectively.
This study aims to determine the effect of concentration of base to ester hydrolysis products. Ester can dihidroisis with an alkaline catalyst at different concentrations. In this study, the concentration of metal acetate used was 1 M NaOH while coud concentration was 0.5 M, 0.75 M, 1 M, 1.25 M. The hydrolysis reaction using ethanol and refluxed for 2 hours at room temperature. Hydrolysis of methyl acetate ester compounds produced methanol with purity varies by different concentrations of methyl acetate and NaOH. At concentrations of 0.5 M NaOH acquired 79.5068% purity methanol, 0.75 M NaOH concentration 85.6665% purity methanol, 1 M NaOH concentration 99.6311% purity methanol and NaOH concentration of 1.25 M purity methanol 100,0000 %. Based on the results of the hydrolysis product purity shows the influence of the concentration of NaOH to the product ester hydrolysis. Methanol compound structure was analyzed by an infrared spectrometer and a mass spectrometer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
