Use of supercritical fluids for different processes including new developments—a revie w

Supercritical fluids have a great potential for wide fields of processes. Extraction processes with supercritical fluids are established even in industrial scale and become again more interesting for industry. Beside this, developments like fractionation of products, dyeing of fibres, treatment of contaminated soils, production of powders in micron and submicron range and reactions in or with supercritical fluids are only a rough extract of possible investigations which will be covered in this paper.
