Quantitative Determination of Completely Acetylated Pentaerythritol and Pentaerythritol Oligomers by High-Performance Liquid Chromatography

Analysis of pentaerythritol (PE) and PE oligomer mixtures has been achieved. PE oligomer mixtures are completely and rapidly (15 min) acetylated using acetic anhydride and a catalytic amount of 4-(dimethylamino)pyridine. A Whatman Partsil-10 C8 HPLC column resolves acetylated PE oligomers, which inc...

Summary:Analysis of pentaerythritol (PE) and PE oligomer mixtures has been achieved. PE oligomer mixtures are completely and rapidly (15 min) acetylated using acetic anhydride and a catalytic amount of 4-(dimethylamino)pyridine. A Whatman Partsil-10 C8 HPLC column resolves acetylated PE oligomers, which include acetylated penta-PE, with a mobile phase of acetonitrile/water (1:1 v/v).
