Solvents are used in most chemical, pharmaceutical and laboratory processes. As a result, their physical and chemical properties provide vital information for their optimal selection. This text contains information on over 250 solvents. It answers key questions including What hazards are connected with the use of a specific solvent? How can the molecular order of a solvent be described? Is water a unique solvent? Which solvent should be selected for my application? It also presents previously uncovered material such as listings of molecular sizes, the concepts of order, softness and acid/base data, thermodynamic, electrical, optical and transport properties.
