Preparation of cellulose acetate produced from lignocellulosic biomass

Abstract

Cellulose acetate is one of well-known industrial materials which have various commercial uses. We treate the lignocellulosic biomass using two-step (steam explosion-chemical) reaction followed by acetylation to get th cellulose acetate in this study. The two-step treatment was done to improve the yields of acetylation of th substrates. The yields of the cellulose acetate were about 88.4, 88.1, and 151.7% in barley straw, rice straw, an oak tree, respectively. Also the degree of substitution (DS) of the acetates was 2.1 to 2.5 in the biomass. W found that the biomass were valuable cellulosic sources, including their derivatives, in this study. This mean that the biomass can be converted into the high-valued cellulosic stuff.
