Book Description :

The phase separation of incompatible liquids has been a topic of significant importance in chemical and industrial engineering for many years. Well-understood examples of this phenomenon include the phase separation of oil with water and the phase separation of non-polar organic solvents with water. Similar behavior is observed when aqueous solutions of two or more incompatible polymers or polymers and salts are mixed. In these mixtures (referred to as aqueous two-phase systems), the separated phases are composed mostly of water. Aqueous two-phase systems have been used extensively for the extraction of high-value biological products from mixtures of biological materials. In recent years, aqueous two-phase systems have also found increased use as materials for streamlining and improving the capabilities of cell and molecular assays, and for the design of advanced cell culture systems. Similar behavior of biological materials in living systems has also been observed, with emerging roles in cell physiology.

Book Description :

Through the current DoE-BES funding, we have extended our fundamental understanding of the critical phase separation of aqueous polymer solutions at the molecular level, and have developed a similar understanding of their application as novel solvent systems. Our principal aims included mode of delivery of the aqueous biphasic system (ABS) solvent system and the application of this system to problems of reactive extraction. In the former case we have developed novel solid phase analogues, in the form of cross-linked polyethylene glycol hydrogels, and in the latter case we have examined the role that ABS might play in reaction engineering, with a view to greener, simpler, and safer processes. We have also developed a new salt/salt ABS and have extended our understanding of this system as well. The major outcomes are as follows: (1) Through the use of variable temperature phase diagrams, coupled with differential scanning calorimetry (DSC) measurements of the phases, a better understanding of the thermodynamics of phase formation was obtained. Evidence to the existence and role of an upper critical solution temperature (UCST) or lower critical solution temperature (LCST) (or both) in these systems was gained. With variable temperature solute partitioning, thermodynamic parameters were calculated, and inter-system comparisons were made. Through the use of Abraham's linear solvation energy regression (LSER) the solvent-solute properties of liquid/liquid ABS were examined. We have shown that ABS are indeed very tunable and LSERs have been used as a tool to compare these systems to traditional organic/water and other liquid/liquid systems. (2) We have successfully shown the development of novel reaction media for chemical synthesis and reaction; Aqueous Biphasic Reactive Extraction (ABRE). As a proof of concept, we have shown the synthesis of adipic acid from cyclohexene in an ABS, which represents an important development in the exploitation of this technology. Previous oxidations of this type have relied on the use of phase transfer catalysts, which are expensive to produce and difficult to recover. In this reaction the polyethylene glycol (PEG) phase seems to function simultaneously as the phase transfer catalyst, the reaction solvent, and to provide the reaction driving force. (3) PEG hydrogels may be used as probes for their macroscopic analogues by which the molecular events underlying the phase behavior of polymer-salt systems can be investigated. The properties of covalently cross-linked PEG hydrogels have been studied. It was demonstrated that these hydrogels could be thought of as analogous to polymer/salt ABS without phase separation. The salts examined cause collapse of the hydrogel, and there is a physical limit to the degree of collapse that can be achieved. In addition, salts bringing about significant collapse are only prevented from reaching this limit by the limits of their own solubility. This lead to our discovery that PEG will phase separate with KSCN at high enough concentration of polymer and salt. We have also successfully shown the development of an IL-PEG hydrogel as well as a Si-modified PEG hydrogel. We have also demonstrated for the first time that this cross-linked PEG matrix has been used to gel non-aqueous solvents. (4) The use of hydrophilic ionic liquids (ILs) in separation schemes has been accomplished via a 'salting out' technique using inorganic, kosmotropic salts that is applicable to many classes of these materials. We have begun to obtain a deeper knowledge about the role that each component plays in the process, including that of the ionic liquid cation and anion, the kosmotropic salt cation and anions, as well as the distribution of water in the system. This is allowing us to design separation systems with desired properties. In addition, temperature studies on these aqueous biphasic systems are revealing thermodynamic data for the first time, so that we can quantitate the importance of e ...

Book Description :

Recoverable and Recyclable Catalysts There is continued pressure on chemical and pharmaceutical industries to reduce chemical waste and improve the selectivity and efficiency of synthetic processes. The need to implement green chemistry principles is a driving force towards the development of recoverable and recyclable catalysts. The design and synthesis of recoverable catalysts is a highly challenging interdisciplinary field combining chemistry, materials science engineering with economic and environmental objectives. Drawing on international research and highlighting recent developments, this book serves as a practical guide for both experts and newcomers to the field. Topics covered include: An introduction to the principles of catalyst recovery and recycling Catalysts on insoluble and soluble support materials Thermomorphic catalysts, self-supported catalysts and perfluorous catalytic systems The development of reusable organic catalysts Continuous flow and membrane reactors Each chapter combines principles with practical information on the synthesis of catalysts and strategies for catalyst recovery. The book concludes with a comparison of different catalytic systems, using case studies to illustrate the key features of each approach. Recoverable and Recyclable Catalysts is a valuable reference source for academic researchers and professionals from a range of pharmaceutical and chemical industries, particularly those working in catalysis, organic synthesis and sustainable chemistry.
