Hi,

Check wikipedia under "Factors influencing the rate of evaporation" at http://en.wikipedia.org/wiki/Evaporatio ... vaporation

Assuming all other things are constant, the properties of the liquid that would have an effect is density, intermolecular forces, and vapor pressure

For vapor pressure, you can learn more about it at
http://en.wikipedia.org/wiki/Vapor_pressure

as well as what "volatility" is at
