Where can I find Heating Values for various VOCs?

Some listed here

Download solid, liquid and gas fuels

Calculate some others



--Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."

Hi,
Try to get a copy of Yaw's handbook of thermodynamic and physical properties of chemical compounds.
Extensive data base.
In case you need:
Good luck

N8Cole,

Write out the combustion chemical formula and use the heats of formation (often found in NIST database) to determine the heat of combustion.

For those that NIST does not have the data (i.e. dimethyl carbonate), I found an online source that estimates the properties as well:

Yes TiCl, most people don't remember J.W. Gibbs

P.E. Metallurgy, consulting work welcomed

Just an example for ethylene carbonate:

C3H4O3(s) + 2.5(O2)(g) -> 3(CO2)(g) + 2(H2O)(l)

Hcomb = (2*HfH2O+3*HfCO2) - (HfC3H4O3+HfO2)
Hcomb = (2*(-285 kJ/mol) + 3*(-393.5 kJ/mol))-(-581 kJ/mol + 0) = -1,169 kJ/mol

Note that this is the standard heat of formation, meaning it is taken at 298 K with all reactants and products in their normal state at 298K.
You can then take the products (water, CO2, etc) and manipulate them to the combustion temperature using heat capacity, heat of vaporization, etc.

Hi,
Heat of combustion C5H9NO: -2994 KJ/mol
Heat of combustion C2H6O2: -7259 btu/lb
Heat of combustion C3H4O3: -1170 KJ/mol
Heat of combustion C5H10O3: -9760 btu/lb.
ETC
A Google search is your ultimate resource or perform calculation as suggested above.

Hi,
My calculation, similar to data found on the net
