Methods and applications of preparative scale chromatography

摘要

A preparative scale chromatographic method in which a mixture is chromatographically fractionated on a sorbent material by the displacing action of a sorbate which is thermally displaced through the material by a heated zone advancing through the material to leave behind sorbent material substantially free of said sorbate. In an application of particular interest, at least one component of the mixture is produced by catalytic reaction of one or more thermally displaced sorbates induced by the heated zone of sorbent material.
