The choice of organic solvent can also have a dramatic effect on selectivity.In contrast to enzyme activity, in the majority of examples reported there appears to be no correlation between solvent physical properties and enantioselectivity. In fact, investigating the effect of various solvents towards a number of lipases, Secundo et al also found that the optimal solvent differed with both enzyme and substrate. A number of theories have been postulated in order to explain these effects in individual cases, but none has any general predictive value. This is somewhat intriguing given that differences in enantioselectivity simply relate to a change in the relative rate of conversion of each enantiomer.

As an example, when determining a solvent s environmental waste score, data are obtained to first score the solvent based on its environmental performance or impacts when it is incinerated, recycled, or undergoes biotreatment. A fourth score is calculated based on the solvent s VOC emissions when handled or used in a process. Some of the data used to determine the basic impact scores include solvent physical property data, waste generation estimations, and ease of operability (in the case of treatment methods). The geometric mean of the four impact area scores yields the environmental waste score. The scores are calculated on a l-to-4 scale and subsequently normalized on a 1-to-lO scale. 10 represents the greenest score and 1 is the least green score for this method [9].
