SYNTHESIS OF ACETATE CELLULOSA FROM THE PALM OIL EMPTY FLOOR THROUGH THE REACTION OF ACTIVATION

Abstract

Acetate cellulose is cellulose whose hydroxyl group is replaced by an acetyl group. Cellulose
acetate has a high enough attractiveness because it is biodegradable so it is environmentally
friendly. The purpose of this study is to increase the acetyl content of cellulose acetate by the
acetylation reaction. This study uses 25 grams of empty fruit bunches to get cellulose, the
delignification process is carried out for 30 minutes with NaOH solution, and the bleaching
process for 1.5 hours with H2O2 solution. Next, as much as 5 grams of cellulose was carried
out by the acetylation process by adding glacial CH3COOH solution, anhydrous CH3COOH
solution with a ratio of 1:10, 1: 12.5 and 1:15 (w / v) and H2SO4 as a catalyst, with
temperature variations of 40oC, 55oC and 70oC. Next, an acetyl concentration was analyzed
by titration, and substitution degree analysis was carried out. The best results obtained from
the two analyzes will be carried out the Fourier Transform Infrared (FTIR) test and the
Scanning Electron Microscope (SEM) test. Acetyl content obtained was 8,152 - 24,58% and
the degree of substitution obtained was 0,3 - 1,2%.
