Fractional-Distillation Microapparatus

Abstract

of the most important operations in organic chemical work is distillation. Several excellent working apparatus have been designed during the past 30 years for fractionating macroquantities of liquids under normal and reduced pressures, among which are those of Kubierschky (4), Friedrichs (2), Widmer (8), Midgley (5), Othmer (6), and Jantzen and Tiedcke (3). The latter, with its specially constructed receiver unit, is widely used as a standard apparatus for the separation of high molecular fatty acids in the form of their esters.
