Recent work on surface tension ¥ò of liquid organic solvents by Egemen et al. (Environ. Sci. Technol. 34, 2596-2600 (2000)) prompts us first to draw attention to a simple correlation at 298 K between ¥ò and bulk isothermal compressibility. While a little less accurate (¡12%) than some available predictions, these later generally involve at least three chemical or physical descriptors to obtain ¥ò. For some 20 organic liquid solvents, the spread of wetting index (again with restriction to 298 K) involving viscosity ¥ç and density ¥ñ is also reported, using the fact that ¥ò/¥ç has units of speed. The search for 'greener' organic solvents may be aided by considerations such as those reported here. The most favourable cleaning agents for the electronic industry require solvents with high density ¥ñ, high compressibility ¥êT, and high velocity vchar (assumed to be equivalent to the sound velocity). |
