What is the heat of combustion of beeswax?
That is how much heat is released in burning beeswax.
Answer should be in units of MJ/kg and a reference link provided. |

I believe this link might have at least part of your answer:

but I'm not familiar enough with the technique involved to be sure
that this is the type of measurement you need. Let me know how close
this comes to what you're looking for.

This gives a measure of the enthalpy of beeswax. This is a distinctly
different physical property than the heat of combustion.
Enthalpy is the internal energy stored in a system during an isobaric process.
Heat of combustion is the heat released when the material is burned.
Good try

How precise an answer are you looking for?
I found heat of combustion values for two waxes: paraffin (42 kJ/g)
and eicosane (48 kL/g). Beeswax would be highly variable, I would
guess, as the composition would change markedly depending on the
source, time of year, mood of the bees, etc. However, I expect it
would be in the ballpark with (but probably lower than) the other two
waxes.

I know that the heat of combustion for beeswax is lower than that of paraffin.
All other physical properties for beeswax have a fairly narrow range
so I would expect that the heat of combustion would also have a narrow
range.
An answer in the form of a range would be acceptable.
A reference link is required.

Hi smoky,
Are you still seeking an answer
to your beeswax question?
thanks,

Yes, I still haven't found a definitive answer.
I will accept an answer in other standard units (i.e. kCal/g) however
I need a link to a reference.
