A typical separation show ing the rectification of a pot charge of aliphatic dimethyl amines is shown above. The product purity of each amine, after dis tillation, was in excess of 99.5%.
Annular spinning Band Distillation column* tor High Purity separations Nester/Faust's new Annular Still employs a Teflon band in annular· configuration for high plate efficiency (in excess of 125 plates), low holdup (0.3 ml) and low pressure drop (3 mmHg at 50 cc boil-up) to produce previously unat tainable rectification. Complete price is under $900. Specifications and application data are contained in Distillation Brochure PIB-65630. Nestor/Faust Glass Products Division, 2401 Ogletown Road, Newark, Delaware.
