Additional information

By measuring the vapour pressure of 2-(2-(2-ethoxyyethoxy)ethoxy)ethanol at various temperatures over the range 152 -257C it was possible to derive the Antoine constants for this substance. By extrapolation using the equation it was possible to predict that the vapour pressure at 20C would be approximately 1Pa.
