Fractional distillation with the bubble tray column with CobraSMARTsense

In countercurrent distillation (rectification) using a column, the rising vapour can enter into interactions with the condensate. In this manner, a fractional distillation, i.e. a distillation in several steps for the separation of substances with similar boiling points, can be performed in a single apparatus. If bubble tray columns are used condensate can be removed from the individual bubble trays. Simplified implementation: all pre-settings already prepared Didactic gas chromatograph included Glass jacket system easily expandable Simultaneous temperature measurement at four points Investigate the mode of operation of a fractionating tower on a two-stage bubble tray column. Distil a mixture of three n-alcanes first with total reflux and then without any reflux. Subsequently, examine and compare the initial mixture, the sump product, the head products and the condensates of both trays.
