Facile and Homogeneous Acetylation of Microcrystalline Cellulose in LiCl/DMAc Solvent System

Cellulose microcrystals were acetylated under homogeneous condition with the aid of DMAP (4-dimethylaminoprydine) and acetic anhydride in LiCl/DMAc( N,N-dimethylacetamide) 1% .three samples with three different amount of acetic anhydride were produced. the obtained cellulose acetates (CA) were characterized by means of Fourier transform infrared spectroscopy (FTIR).therefore, this study presents a promising approach and facile method for cellulose acetylation
