STATISTICAL ANALYSIS OF CALORIMETRIC EXPERIMENTAL RESULTS OBTAINED FROM THE COMBUSTION OF ETHYL ALCOHOL IN AN OPEN SYSTEM

This paper presents the results obtained in the determination of the heats of combustion of some aliphatic alcohols by the open-system calorimetric method, their comparative analysis and the correlation of these results with the formula and molecular structure of the alcohols. Following the correlation of the calculations and statistical analysis, it was observed that the heats of combustion increase with the increase of the chain, i.e. the number of carbon atoms. Also, alcohols with a branched chain molecule:iso-propanol, iso-butanol had a slightly higher heat of combustion than the linear chain isomers: n-propanol, n-butanol.
