Liquid vapour pressure

This is a sample of the liquid vapor pressure calculator. To access the working calculator, please sign up for free membership trial.

The application presented here can be used to calculate vapour pressures of various organic and inorganic substances at a specified temperature. For any sunstance the temperature must be within an applicable range displayed upon the selection of liquid. The vapour pressures given here are in "KiloPascal (kPa)" and temperatures are in "Kelvin (K)". Use the unit converter to operate with your preferred units.

An easy way of browsing this list is to know the type of substance you are looking for. In a descending order this list presents Alkanes, Alkenes, Alkynes, Cycloalkanes, Aromatics, Alcohols, Ethers, Aldehydes, Ketones, Organic Acids, Esters, Amines, Amides, Nitriles, Organic Sulphides, Haloalkanes, Haloaromatics and a small group of inorganic compounds at the end.

Select Liquid from the list:
Minimum applicable temperature = K
Maximum applicable temperature = K
Calculate the vapour pressure at temperature = K
Vapour pressure = kPa
