| dc.description.abstract | The production of methyl cellulose was carried out through an etherification reaction between α-cellulose isolated from bagasse (Saccharum officinarum L.) and dimethyl sulfate. α-cellulose was carried out by adding 3.5% HNO3, 2% NaOH and Na2SO3, 1.75% NaOCl, 17.5% NaOH and 10% H2O2, 18 g of α-cellulose was obtained (32% of the initial weight). Methyl Cellulose is made by adding NaOH, isopropanol solvent and dimethyl sulfate. The temperature and NaOH are 46OC, 51OC, 56OC and 10%, 15%, 20%. Results of manufacture of methyl cellulose analysis with FT-IR spectrophotometer, surface morphology using SEM and Degree of Substitution. Methyl cellulose which has the highest degree of substitution at a temperature of 56OC and 10% NaOH of 1.22 Degree of Substitution. The formation of methyl cellulose at 56OC and 10% NaOH was supported by the FT-IR spectrophotometer, namely the appearance of a vibrational peak in the region of wave number 3442.9 cm-1 showing -OH groups, C-H groups stretching at wave number 2897.6 cm-1, Absorption peaks indicating the presence of C-O-C were found at wave numbers 1155.3 cm-1 and 1028.0 cm-1 which were asymmetrical and symmetrical stretching vibrations, respectively. The results of surface morphology analysis with SEM showed that the fiber surface on methyl cellulose was smoother than cellulose. | en_US |
