One variety of this technique utilizes a short-path apparatus called a Kugelrohr (KOO-gehl-roar).
One variety of this technique utilizes a short-path apparatus called a Kugelrohr (KOO-gehl-roar). Teflon flaps are used in another apparatus, a Perkin triangle, to perform this technique on air-sensitive materials. The pressure-swing type of this process is used on azeotropic mixtures, while the vacuum type of this process reduces the ambient pressure until it drops below the (*) vapor pressure. When component parts boil at less than 25 degrees Celsius from each other, such as for crude oil, the fractional type of this technique is employed. Often applied to air, alcoholic beverages, and seawater, this is, for ten points, what technique whereby components of a mixture are separated based on their boiling points?
