SUPERKRITISCHE FLUIDE ODER DICHTE GASPHASEN AUS FLÜSSIGEN VORLÄUFERN

摘要

A gas or mixture of gases is produced by decomposition or chemical reaction of liquid precursor(s). The gas may be converted to a dense phase gas or supercritical fluid state which can be used as a medium for chemical reaction, chromatography, extraction or impregnation/modification. Changes in the gas composition may be made simply by modification of the metered flow rates or chemical composition of the liquid precursor(s).
