Pharmaceutical and fine chemical products are typically synthesised batchwise which is an anomaly since batch processes have a series of practical and economical disadvantages. On the contrary, flow continuous processes present a series of advantages leading to new ways to synthesise chemical products. Flow processes - * enable control reaction parameters more precisely (temperature, residence time, amount of reagents and solvent etc.), leading to better reproducibility, safer and more reliable processes * can be performed more advantageously using immobilized reagents or catalysts * improve the selectivity and productivity of the process and possibly even the stability of the catalyst * offer opportunities for heat exchange and energy conservation as well as an easy separation and recycling of the reactants and products by adequate process design * achieve multistep syntheses by assembling a line of reactors with minimum or no purification in between two reaction steps * can be assured by facile automation * scale-up can be easily conducted by number-up With all the new research activity in manufacturing chemical products, this comprehensive book is very timely, as it summarises the latest trends in organic synthesis. It gives an insight into flow continuous processes, outlining the basic concepts and explaining the terminology of, and systems approach to, process design dealing with both homogeneous and heterogeneous catalysis and mini- or micro-reactors.

CO2-responsive materials are a relatively recent innovation. In general, stimuli-responsive materials exhibit reversible changes in their physical or chemical properties in response to external triggers such as temperature, pH, light, or voltage. However, there are often limitations in applying these triggers including economic and environmental costs, and product contamination. The realization that CO2 can be used as an effective trigger for stimulating changes in material properties has prompted a surge in interest in this area within the past few years, with numerous new studies currently underway in several countries. CO2 is an ideal trigger for switchable or stimuli-responsive materials because it is benign, inexpensive, green, abundant, and does not accumulate in the system. Many different CO2-responsive materials including polymers, latexes, solvents, solutes, gels, surfactants, and catalysts have been prepared. Summarizing recent progress in the preparation, self-assembly, and functional applications of CO2-responsive materials, this book explores the physical chemistry of CO2-switching, including constraints on structural design and process conditions, together with applications. With emphasis on the environmental, health, and safety advantages and disadvantages compared to conventional materials, it is ideal for researchers and industrialists working in green chemistry, chemical engineering, and polymer chemistry.
