Different opinions can be found about the status of analytical chemistry as being a branch of chemistry independent from other chemical disciplines or being a physical discipline (Green [ 1992]), or even being an autonomous science, occasionally called Analytics or Analytical Sciences. On the other hand, wide agreement can be stated about the aim to obtain information on matter via representative samples and the inclusion of structural information. Remarks on the general importance of analytical signals can be repeatedly found.

Formulation Requirements. In order to penetrate the mass of fiber at one end of the bundle, the formulation must have sufficiently low viscosity to move easily through the bundle completely wetting all fiber surface area. Typically, formulations of viscosity less than 8000 poises have been successful. Too low viscosity or too rapid delivery of the formulation can result in the occlusion of air and the ultimate development of voids with loss of mechanical integrity. Our process demands that formulation be delivered and partially cured to an intermediate plateau termed green state. This requires a minimum pot life of 30 minutes after blending of resin and curative. The physical chemistry of the composite membrane requires that the initial exotherm not exceed approximately 150 C. 

As defined previously, risk is a function of hazard and exposure. In the environmental risk context, hazard is a function of toxicity which is affected by physical/chemical and environmental fate properties and hence chemistry. Green chemistry reduces the risk or environmental impact of processes or products by focusing on the hazard component. 

Detailed recommendations from the International Union of Pure and Applied Chemistry (IUPAC, http //www.iupac.org) are given in the book titled Quantities, Units and Symbols in Physical Chemistry, 2nd edition, nicknamed the green book , published by Blackwell Science, Oxford, U.K., 1993. Updates are published as articles in the journal Pure and Applied Chemistry. 

The first IUPAC Manual of Symbols and Terminology for Physicochemical Quantities and Units (the Green Book) of which this is the direct successor, was published in 1969, with the object of securing clarity and precision, and wider agreement in the use of symbols, by chemists in different countries, among physicists, chemists apd engineers, pnd by editors of scientific journals . Subsequent revisions have taken account of many developments in the field, culminating in the major extension and revision represented by the 1988 edition under the simplified title Quantities, Units and Symbols in Physical Chemistry. 

Schmidt s work emphasized the point that the physical and chemical properties of crystalline solids are as critically dependent upon the distribution of molecular components within the crystal lattice as the properties of its individual molecular components. In other words, crystal engineering is not only a scientific challenge, there are significant technological implications, in particular in the context of the development of solvent free chemistry ( green chemistry ) and materials science.

We have tried to cover important aspects of the physical chemistry of the ionic liquids currently under study, and to relate them to what is known about other types of low-melting ionic media. In concluding, we must emphasize that much of the success in their application, particularly in the Green Chemistry area where there is hope they will replace volatile solvents of environmentally hostile character, will depend on the important chemical properties of these media. These we have not addressed at all in this chapter. Properties such as donor and acceptor character, acidity and basicity, are in fact aU within the capacity of physics to describe, though they are most commonly invoked in a more empirical manner based on experience, as described in [1—4]. An excellent treatment of acid base character of ionic liquids has recently been given by MacFarlane and Forsyth [45].
