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 .
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.
Heat of Combustion for Blends of Kerosene with Alcohols Comparison of Kerosene Blends with Pure Alcohols: Pure methanol and ethanol have heating values of 16.3- 6MJ/Kg and 21.6MJ/Kg respectively.
Combustion is a chemical reaction in which oxygen gas is a reactant. Combustion reactions can be classified as complete combustion or as incomplete combustion. Complete Combustion of alcohols: ⚛ Excess O 2 (g) is present to react. ⚛ Reaction products are CO 2 (g) and H 2 O (g) . ⚛ alcohol + oxygen gas → carbon dioxide gas + water vapour.
All the combustion reactions from the alcohols will be exothermic; exothermic is a process that releases heat, in an exothermic reaction, the enthalpy of the reacting system decreases is negative. In an endothermic reaction, the enthalpy of the reacting system increases is positive.
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.

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.
