  2. Reflux - Wikipedia

    en.wikipedia.org/wiki/Reflux

    Inside the column, the downflowing reflux liquid provides cooling and condensation of the upflowing vapors thereby increasing the efficiency of the distillation column. The more reflux provided for a given number of theoretical plates, the better is the column's separation of lower boiling materials from higher boiling materials. Conversely ...

  3. Dean–Stark apparatus - Wikipedia

    en.wikipedia.org/wiki/Dean–Stark_apparatus

    It is used in combination with a reflux condenser and a distillation flask for the separation of water from liquids. This may be a continuous removal of the water that is produced during a chemical reaction performed at reflux temperature, such as in esterification reactions. The original setup by Julius Marcusson (invented in 1905) was refined ...

  4. Condenser (laboratory) - Wikipedia

    en.wikipedia.org/wiki/Condenser_(laboratory)

    Distillation setup using a retort and tube condenser, from a 1921 book. [5] The simplest type of condenser is a straight tube, cooled only by the surrounding air. The tube is held in a vertical or oblique position, and the vapor is fed through the upper end. The heat of condensation is carried away by convection.

  5. Perkin triangle - Wikipedia

    en.wikipedia.org/wiki/Perkin_triangle

    A Perkin triangle is a specialized apparatus for the distillation of air-sensitive materials. It is named after William Henry Perkin Jr. , whose design was approximately triangular . [ citation needed ] The diagram shows a more modern version, in which the glass taps have been replaced with more air-tight Teflon taps.

  6. Soxhlet extractor - Wikipedia

    en.wikipedia.org/wiki/Soxhlet_extractor

    A Soxhlet extractor has three main sections: a percolator (boiler and reflux) which circulates the solvent, a thimble (usually made of thick filter paper) which retains the solid to be extracted, and a siphon mechanism, which periodically empties the condensed solvent from the thimble back into the percolator.

  8. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    The azeotrope is easily broken in a distillation set-up by using a liquid–liquid separator (a decanter) to separate the two liquid layers that are condensed overhead. Only one of the two liquid layers is refluxed to the distillation set-up. High boiling azeotropes, such as a 20 percent by weight mixture of hydrochloric acid in water, also ...

  9. Batch distillation - Wikipedia

    en.wikipedia.org/wiki/Batch_distillation

    Diagram of a Batch Rectifier. The simplest and most frequently used batch distillation configuration is the batch rectifier, including the alembic and pot still.The batch rectifier consists of a pot (or reboiler), rectifying column, a condenser, some means of splitting off a portion of the condensed vapour (distillate) as reflux, and one or more receivers.
