Abstract
Cellulose acetate is a cellulose derivative that has high commercial value and wide applications in various industries such as textiles, plastics, and coatings. This study aims to synthesize and analyze the characteristics of cellulose acetate derived from kapok fiber (Ceiba pentandra) using the solution process method. The synthesis process includes delignification, bleaching, activation, acetylation, and hydrolysis stages. The variables examined in this research were the volume of glacial acetic acid (8–40 mL) and the acetylation time (60–150 minutes). The analysis results show that the highest acetyl content of 39.92% was obtained at an acetylation time of 90 minutes and an acetic acid volume of 40 mL, with a degree of substitution reaching 2.466, which falls into the category of diacetate cellulose according to the Indonesian National Standard (SNI). The FTIR spectrum indicates the presence of functional groups characteristic of cellulose acetate, such as C=O and C–O from the acetyl group. This study demonstrates that kapok fiber is a potential raw material for producing high-quality cellulose acetate.
