Vapour Pressure of Biodiesel

Vapour Pressure of Biodiesel

Vapour Pressure of Biodiesel

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

RE: Vapour Pressure of Biodiesel

At what temperature?

RE: Vapour Pressure of Biodiesel

(OP)
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.

RE: Vapour Pressure of Biodiesel

(OP)
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?

RE: Vapour Pressure of Biodiesel

Can you calculate Pvap by using Antoine equation ?

RE: Vapour Pressure of Biodiesel

(OP)
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.

RE: Vapour Pressure of Biodiesel

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

In perry chemical handbook for example?
