Supported Ionic Liquids

Technology with supported ionic liquids is a fundamental new approach to modifying the surfaces of porous solids by dispersing a thin film of ionic liquid onto it. The technology allows introducing new and unique material properties and attains long-term stable materials. Divided into four parts, this book introduces the topic of supported ionic liquid materials and fundamentals, covering ionic liquids, porous supports, synthesis and characterization. The main part covers various applications, such as the catalytic production of bulk and fine chemicals, environmental processes, biotechnology, energy production and gas separation. In each case, the most pertinent authors available describe here the underlying research. The final part discusses the perspectives and outlook of these materials as well as describing some real life applications.

This book is aimed at organic and inorganic chemists, industrial chemists, catalytic chemists, chemical engineers, biotechnologists, materials scientists and libraries
