Title: Improvements in distillation of heat sensitive compounds
Inventor: SKINNER BRADLEY
IPC: B01D3/34
Filed: 1958-04-03
Abstract: A process for the purification of a mixture of compounds containing at least one heat-sensitive compound comprises passing a diluent gas through the bottom tray of a distillation column to drive substantially all of the mixture upward, vaporizing a major portion of said mixture by heat supplied by indirect heat-exchange immediately above said bottom tray and collecting unvaporized material at the centre of the bottom tray.  The process may be used to separate 2-methyl-5-vinyl-pyridine from 2-methyl-5-ethyl-pyridine, and styrene from benzene, toluene, ethyl benzene, isopropyl benzene, diethyl benzene, allyl benzene, phenyl acetylene or naphthalene. Other substances which may <PICT:0830772/III/1> be separated include vinyl and alpha-methyl substituted quinolines, isoquinolines, piperidines, pyrroles, pyrrolidines, pyrrolidones, alkyl derivatives of the foregoing compounds, dihydro and tetrahydropyridines, including partially hydrogenated quinolines and isoquinolines.  In a typical example, a stream containing water, 2-methyl-5-vinylpyridine, 2-methyl-5-ethylpyridine, and lower boiling components was introduced into a column 2 at a point about half-way up the column, and the higher boiling material descends to a tray 4. Steam or other inert gas from a line 8 enters zone 6 and passes through orifices 20 causing vaporization of most of the feed. Further indirect heating is provided by means of reboiler tube bundles 12.  The liquid product is withdrawn via an insulated line 14 and a monometric trap 16 and is withdrawn from a pipe 18.  The overhead products consist of 2-methyl-5-ethylpyridine and water.
