SUPERCRITICAL FLUIDS OR DENSE PHASE GASES FORMED FROM LIQUID PRECURSORS

Title:

SUPERCRITICAL FLUIDS OR DENSE PHASE GASES FORMED FROM LIQUID PRECURSORS

Document Type and Number:

WIPO Patent Application WO2002078832

Kind Code:

A3

Abstract:

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).
