Book Synopsis Extraction of Natural Products Using Near-Critical Solvents by : M.B. King
Download or read book Extraction of Natural Products Using Near-Critical Solvents written by M.B. King and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to present the current state of the art of extracting natural products with near-critical solvents and to view the possibilities of further extensions of the technique. Relevant background theory is given but does not dominate the book. Carbon dioxide is the near-critical solvent used in most recent applications and inevitably receives prominence. In addition to general descriptions and reviews, the book contains three chapters by indus trial practitioners who describe in detail the operation of their processes and discuss the market for their products. Sections on the design of the pressure vessels and pumps required in these processes and on the acquisition of the data required for design are included. The costing of the processes is also discussed. There is good scope for combining a near-critical extraction step with other process steps in which the properties of near-critical solvents are utilised, for example as a reaction or crystallisation medium and a chapter is devoted to these important aspects. It is hoped that the work will be found to contain a great deal of specific information of use to those already familiar with this field. However the style of presentation and content is such that it will also be useful as an introduction. In particular it will be helpful to those wondering if this form of separation method has anything to offer for them, whether they are engineers, chemists or managers in industry, or in academic or research institutions.

The overview includes the fundamentals, industrial applications, and main experimental findings based on recent studies about supercritical extraction using carbon dioxide. Next, the impregnation of polymer materials with two different ketones with known activity against the main pests of stored products (thymoquinone and R-( )-pulegone) is presented, and the effect of the process variables on ketone loading and the final activity of the impregnated materials is discussed. The authors go on to evaluate the effect of temperature (T: 41-69°C) and CO2 density (D: 843-957 kg/m3) on the extraction yield of oil and bioactive compounds of N. gaditana using supercritical CO2, a technology that allows for the selective extraction of compounds of interest by varying the pressure and temperature conditions, producing natural extracts without the use of liquid organic solvents. Hydrophobic modifying coatings on textile materials made of polyethylene terephthalate were obtained by precipitating a low molecular weight fraction of ultrafine polytetrafluoroethylene. The modifier application conditions are also defined.
