brj-22367	Ma'ruf, Anwar; Purnawanto, Agus Mulyadi Purnawanto; Rimatunnisa, Rizka	The Synthesis of Cellulose Acetate from Rice Husk Cellulose by Ultrasound-Assisted Acetylation	2023	11	.pdf	application/pdf	3817	223	54	The results showed that the optimum yield of cellulose acetate was obtained at the temperature of 60 °C, the reaction time of 50 min, the weight of the catalyst of 10% of cellulose weight, and the ratio of cellulose and acetic anhydride of 1:5 (w/v). The optimum yield of cellulose acetate obtained was 120%, and the process condition for maximum yield was a temperature of 60 °C, a reaction time of 50 min, and a catalyst weight of 10% of cellulose weight.	cache/brj-22367.pdf	txt/brj-22367.txt
