Parameter, productivity general discussion

Generally, the environmental risk of ionic liquids can be described as the product of exposure and hazard of a given coirpound. Even if the main exposure pathways, the ejq)ected technological uses and the amounts and distributions of certain ionic liquid structures in different environmental conpartments do still remain unclear, we have tried to address the exposure level by discussing the degradability and persistency of ionic liquids. The hazard potential of ionic liquids as the second important risk parameter can be discussed on the basis... 

This section will discuss some of the adjustable parameters in method development that are critical to successful process development. As a general approach these parameters are best examined on analytical scale before increasing the scale to something approaching production size for several reasons ... 

Of the three general categories of transport processes, heat transport gets the most attention for several reasons. First, unlike momentum transfer, it occurs in both the liquid and solid states of a material. Second, it is important not only in the processing and production of materials, but in their application and use. Ultimately, the thermal properties of a material may be the most influential design parameters in selecting a material for a specific application. In the description of heat transport properties, let us limit ourselves to conduction as the primary means of transfer, while recognizing that for some processes, convection or radiation may play a more important role. Finally, we will limit the discussion here to theoretical and empirical correlations and trends in heat transport properties. Tabulated values of thermal conductivities for a variety of materials can be found in Appendix 5.
