Gases and gas mixtures typically capable of conversion to supercritical fluids or dense phase gases formed from liquid precursors, apparatus for making said gases and gas mixtures, and products made using them

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).
