Xenon occurs in slight traces in gases within Earth and is present to an extent of about 0.0000086 percent, or about 1 part in 10 million by volume of dry air. Like several other noble gases, xenon is present in meteorites. Xenon is manufactured on a small scale by the fractional distillation of liquid air. It is the least volatile (boiling point, −108.0 °C [−162.4 °F]) of the noble gases …

Ramsay and his coworkers searched for related gases and by fractional distillation of liquid air discovered krypton, neon, and xenon, all in 1898. Radon was first identified in 1900 by German chemist Friedrich E. Dorn; it was established as a member of the noble-gas group in 1904. Rayleigh and Ramsay won Nobel Prizes in 1904 for their work.

Jul 08, 2021 · Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still. It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids.
