Applications of supercritical fluid extraction

Based on the overwhelming prevalence of CO, as SF extractant, all applications described in this section refer to this fluid (whether neat or modified by a cosolvent) unless otherwise stated. Because of its special features, the uses of supercritical water are dealt with in another section. [Pg.328]

Based on the number of reported applications, the unequivocal establishment of its scope, advantages and disadvantages from the results of such applications, and the inception of automated coupled systems [132,133], supercritical fluid extraction has already come of age. [Pg.328]

For the underlying science of supercritical fluids, try Steve Howdle s short article Supercritical solutions in Chemistry in Britain, August 2000, p. 23, which represents a useful introduction to the topic. For more applications of such fluids, try the short review article Some applications of supercritical fluid extraction , by D. P. Ndiomu and C. F. Simpson in Analytica ChimicaActa, 1988,213,237. The article is somewhat dated now but readable. A look at the contents list of The Journal of Supercritical Fluids will be more up-to-date go to http //www.umecheme. maine.edu/jsf. [Pg.545]

The microwave assisted extraction for organic compounds including polyaromatic hydrocarbons, phenols and organochlorine insecticides, described in section 11.1.8 [25] has been applied to sediments. The application of supercritical fluid extraction to the determination of various insecticides in soils described in section 11.1.7 [23] has been applied to river sediments. [Pg.306]

Applications of supercritical fluid extraction and headspace analysis are, however, now creeping in. Thus supercritical fluid extraction with carbon dioxide-methanol has been used to extract 2,4-chlorophenol from crops [231 ], sulfonylurea herbicides from plants [161], and organophosphorus pesticides from fruit and vegetables [226].

Plants and plant extracts have been used as medicine, culinary spice, dye and general cosmetic since ancient times. Plant extracts are seen as a way of meeting the demanding requirements of the modem industry. In the past two decades, much attention has been directed to the use of near critical and supercritical carbon dioxide solvent, particularly in the food pharmaceutical and perfume industries. CO2 is an ideal solvent because it is non-toxic, non-explosive, readily available and easily removed from the extracted products. At present the major industrial-scale applications of supercritical fluid extraction (SFE) are hop extraction, decaffeination of coffee and tea, and isolation of flavours, fragrances and other components from spices, herbs and medicinal plants [1-4].

The same team, Sedlakova et al. (2003 a), has investigated the application of Supercritical Fluid Extraction for the essential oil determination in small samples gathered during breeding as an alternative method. The results were used as a one of the criteria during breeding. Classical way of the essential oil determination does not allow this option. Table 6 shows the essential oil content in Czech varieties and different essential oil composition of some European caraway resources is mentioned in table 7. [Pg.11]

Equilibrium phase diagrams for one or more solutes in supercritical CO2 and other solvents can be very complicated. Relatively little equilibrium information has been published this lack coupled with the cost of high-pressure equipment and the difficulties of scaleup have to date limited the commercial applications of supercritical fluid extraction.
