Cellulose triacetate, acetylated-paper

The starting material for this process is wood pulp, cloth, or paper waste and the acetic acid is added first to swell the material and allow it to take up the reagents better. Organic solvents often do this to polymers. The anhydride now carries out the acid-catalysed acetylation and the cellulose triacetate, unlike the cellulose, dissolves in the reaction mixture. The new polymer is often known simply as acetate . 

The first paper on noncommercial plates of cellulose triacetate for the Troger s base enantiomeric separation was published in 1973 [11], Later, applications on commercial cellulose triacetate plates containing a fluorescent indicator (Antec, Switzerland) and on cellulose triacetate at 20, 30, and 40% acetylation degree (w/w) were carried out. However, the use of these plates was limited by their little success using different solvent systems.
