Abstract
A novel packing material has been developed for fractional distillation: a spiral-wound, high-surface-area brush. The “Texas brush” packing provides exceptionally easy use and consistency. Fractions collected for the classical boiling point versus volume plot were analyzed by 1H NMR for absolute identification of components and for quantitation. The 1/2 in. brush has a 2.3 in. HETP (height equivalent of a theoretical plate) at a reflux ratio of 22.
