Use of alternative reaction media for an environmentally safer chemical production. The way in which a chemical reaction is carried out and the composition of the reaction mixture diotate the degree of difficulty of downstream processing operations, not only in terms of energy consumption but also with respect to environmental pollution. A specific environmental protection that is an integral part of the production process must therefore begin with the examination of the chemical rection step. Restructuring a process from a reaction engineering point of view includes two important aspects of which the technical implementation has not yet been systematically examined and which therefore should promise a significant potential for innovation. These are the integration of modern separation operations in the chemical reactor with the aim of shifting the chemical equilibrium and the choice of an alternative reaction medium; although the latter also serves the same purpose, it can bring about a significant reduction in environmental pollution. This aspect is the focus of this paper, in which the advantages of molten salts, supercritical fluids and microemulsions as alternative reaction media are discussed.
