Abstract
An alternative path for the preparation of triacetylcellulose (TAC) from unrefined biomass Palm Empty Fruit Bunch (EFB) has been found with environmental benefits. The method comprises separation and regeneration of cellulose from lignocellulosic biomass dissolved in ionic liquid BMIMCl, and also modification of cellulose to TAC. The triacetylcellulose with a degree of substitution of 2.93 was obtained by the reaction of acetic anhydride at 55 。 C with drastically reducing number of steps currently required to produce this derivative from raw materials itself. TAC was characterized using NMR analysis. The triacetate cellulose is typically used for the creation of fibers and film base.
