Vapour Pressure of Biodiesel

[cajar]

What is the vapour pressure of biodiesel produced from palm oil or tallow? Or really from any oil if it is know.

 

[SeanB]

At what temperature?

 

[cajar]

We have a variety of temperatures between 30 and 80degC (86-176degF). So any vapour pressures you have in this range would be really useful.

Thanks but isnt the vapour pressure different depending on the type of oil used in the process? Or are they going to be small that it doesnt really matter?

Can you calculate Pvap by using Antoine equation ?

 

[cajar]

I have been using that equation to calculate the vapour pressure for the other components in the system, but i can't find the co-efficients for this substance.

Can you find a component with almost similar thermodynamic properties and do an approximation calculation?

In perry chemical handbook for example?
