Rectified spirit, also known as neutral spirits, rectified alcohol, or ethyl alcohol of agricultural origin is highly concentrated ethanol that has been purified by means of repeated distillation in a process called rectification. In some countries, denatured alcohol or denatured rectified spirit may commonly be available as "rectified spirit". A Rectified Spirit Alcohol is highly concentrated ethanol which is obtained by fractional distillation, a process that is called rectification. Rectified Spirit Alcohol typically contains 95% v/v the purity of rectified spirit has a practical limit of 95.6% v/v (191.2 US proof) when produced using conventional distillation processes, because a mixture of ethanol and water becomes an azeotrope at this concentration. Rectified spirit, also known as neutral spirits, rectified alcohol, or ethyl alcohol of agricultural origin is highly concentrated ethanol that has been purified by means of repeated distillation in a process called rectification. It is a simple alcohol with the chemical formula C2H6O. Its formula can be also written as CH3CH2OH or C2H5OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH.
