ABSTRACT:
The preparation of microcrystalline triacetylcellulose by acid-catalyzed acetylation of microcrystalline cellulose, perfluoroalkanesulfonic acids with 1 to 8 carbon atoms are used as the catalyst, resulting in a non-hazardous process and high yields of exceptionally high purity product, the latter being particularly suitable for chromatographic purposes, in particular for the chromatographic resolution of racemates.
