Enthalpy of combustion alcohols data

Enthalpy of combustion KJ mol-391.27-246.61-449.20-141.10-528.12-1003.79. This table shows the results of the six different alcohols and also it is showing the enthalpy of combustion. I have worked out the enthalpy of combustion using formulas in Microsoft excel. Look at graph 1. By looking at this graph you can see that there are 2 anomalous ...

May 08, 2013 · It can be taken further if used with post-16 students who can calculate values for enthalpy changes of combustion, with subsequent discussion about heat losses and incomplete combustion. The alcohols should be provided in labelled spirit burners ready to use.
Alcohols, too, take many forms and have various levels of complexity, but we're concerned mainly with ethanol (grain-derived alcohol) and - just in passing - methanol (wood- or cellulose-derived alcohol). These two alcohols are the only practical alcohol fuels ... and of the two, ethanol is more economically feasible on a small scale.

tert-Butyl alcohol is the simplest tertiary alcohol, with a formula of (CH 3) 3 COH (sometimes represented as t -BuOH). It is one of the four isomers of butanol. tert -Butyl alcohol is a colorless solid, which melts near room temperature and has a camphor -like odor. It is miscible with water, ethanol and diethyl ether .
From looking at the data collected, it strongly supports the alternative hypothesis as the alcohol group with more carbon atoms (propanol) has a more negative standard enthalpy change of combustion (propanol is -448.315kJ/mol while ethanol is -234.88kJ/mol).
Sometimes the problem will be silent about what type of compound it is, give only C and H data, but oxygen will also be in the compound. See comment in Example #3. Example #2: A 0.250 g sample of hydrocarbon undergoes complete combustion to produce 0.845 g of CO 2 and 0.173 g of H 2 O.
The standard enthalpy of combustion of methanol including uncertainty is: 24.59 kJ/mol ± 3.60 kJ/mol. The same procedures were made for the other 4 alcohols to calculate the standard enthalpy of combustion of alcohols including uncertainties and the results were put into the table on the next page. Conclusion:

Ethanal (common name acetaldehyde) is an organic chemical compound with the formula CH 3 CHO, sometimes abbreviated by chemists as MeCHO (Me = methyl).It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry.
