Green Sustainable Process for Chemical and Environmental Engineering and Science: Ionic Liquids as Green Solvents discusses the application of ionic liquids as environment-friendly solvents in the extraction, separation and purification of organic and inorganic compounds, as reaction media in biochemical and chemical reactions and catalysis, and in green organic and drug syntheses. It covers various industrial applications, from polymer synthesis, to biodiesel and lubrication, paint and pigments, water softening and dry-cleaning, ore refining, the nuclear industry, aerogels, fuel cells, and more. Specific sections cover hydrogenation, oxidation, hydroformylation, acylation, acetylation, dimerization, oligomerization, photochemical and cleavage of ethers reactions. The book's main emphasis lies in the extraction and separation of biomolecules, vitamins, proteins, enzymes, and DNA using ionic liquids as green solvents. High-performance thin layer chromatography and gas chromatography are also discussed.
