Vapor Pressure of Common Alcohols
The vapor pressure of alcohols refers to the pressure exerted by the vapor (gaseous phase) of a particular alcohol when it is in equilibrium with its liquid phase at a given temperature. The following table provides a curated list of vapor pressure values for various alcohols under 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
