Solvents have been traditionally chosen on the basis of whether they can do the job effectively and economically but other factors now have to be taken into consideration. Regulations relating to the exposure to solvent vapours have become more stringent - hence the importance of choosing the best solvent for the job as early as possible in the process. This book sets out the physical properties of the fifty most commonly used solvents, along with information on their behaviour during and after use, health and fire hazards, the photochemical ozone creation potential (POCP), and recovery processes including practical aspects of the design and operation of batch stills.
