Separation of Some Benzene Derivatives by Gas – liquid Chromatography

Abstract

Using chromatographic column of glass beads coated with solid lithium nitrate and
modified by water vapor in the Helium carrier gas can be used at room temperature give a
highly efficient separation, in a reasonable time of range (10-40) min., mixture containing
different types of xylene and some benzene derivatives. The column glass beads used were
(40 / 50 ) mesh . Its high separation efficiency was obtained compared with conventional gas
– liquid chromatography.
