Ethanol is a simple hydrocarbon of the molecular formula C2H5OH. Ethanol is a form of primary alcohol. This can, then, be oxidised to carboxylic acid by refluxing it with an acid (H+) and potassium dichromate. Ethanol can also be oxidised to ethanal through partial oxidation. This is achieved by adding excess alcohol and by distilling off the aldehyde as it forms[1]. Ethanol is used commonly as a solvent and is used in, both, the perfume and paint industry. It is also used to dissolve a wide range of water-insoluble medications[2].
