Microscale Distillation Short Path

Apr 07 2022nbsp018332This shortens the path length between distilling and receiving flaskIt can be used for 5 10 mL of materialThe distillation needs to be done with care as too high of temperatures may cause vapor to be lost out of the vacuum adapter.

It is a process of separation purification and concentration of natural products complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acidsThis process is characterized by short term exposure of the distillate liquid to high temperatures in high vacuum around 104 mmHg in the distillation column and a small distance between the evaporator and the condenser around 2 cmIn molecular distillation fluids are in the free molecular flow regime iThe mean free path of molecules is comparable to the size of the equipment.

Nov 03 2014nbsp018332Short path and molecular distillation were developed in the 1930s and 1940s mainly in the UK and in the USAIn short path distillation the produced vapours do not have contact with the liquid any moreThe number of theoretical stages is 1 at a small distillate rate and may rise up to 2.

Sep 28 2017nbsp018332Shortpath distillation can be very chemically abrasive to your vacuum pump so it’s imperative to own a chemically resistant vacuum pump to achieve extreme depthThe pump should reach at least 50 microns—but the deeper the betterThe preferred type of pump for distillation is a rotary vane oil pump to help with this.

Shortpath microscale distillations are carried out using the Hickman distillation head as the receiving device for the distilled liquidTwo types of Hickman head ported and unported are shown in the figure belowThe complete apparatus consists of a flask or vial containing the liquid and a magnetic spin vane or boiling stone attached to the bottom joint of the Hickman head.

The distillate is collected in a 175mL glass vial that is tightened with an Oring or a rubber gasket simply made from a rubber sheet using a cork borerThe purity of the product is controlled by refractive index or a microscale boiling point determinationThis apparatus has been used in our student laboratories with very good results.

The distillation rates can be achieved within the pressure and temperature range of 1 to 1x103 mbar and 150176C to 280176C respectively.
