Assessment of the homologous series for the hydroxyl functional group in combustion systems

  Harsh Agarwal

Enthalpies of combustion of alcohols are used by manufacturers in the petroleum industry to compare the efficiency and heating value of fuels as well as the stabilities of chemical compounds. The tribology investigation seeks to explore the effect of the position of alcohol in the homologous series on its standard enthalpy of combustion. Under laboratory conditions, four alcohols – methanol, ethanol, propanol, butanol – were viable to be experimented with. An insulated calorimeter and spirit lamp along with other supplementary apparatus served as the heating tools. The temperature rise was measured for 5 trials per alcohol and with the help of the raw data, the standard enthalpy of combustion for each alcohol was mathematically deduced. A clear positive relationship between the number of carbon atoms in the alcohol molecule and its standard enthalpy of combustion existed thus, the data was reliable with respect to its scope and methodology; however, a percentage error accompanied the calculations.
