Ethanol

hemical name Ethanol, Ethyl alcohol chemical formula C2H6O molecular mass 46.07 g/mol CAS number 64-17-5 EINECS number 200-578-6

boiling point 78°C Relative density 0.805 - 0.812% v/v melting range -114.3°C

At ambient temperature it is a colourless liquid, clear, with a characteristic odour, volatile (boiling point 78°C), hygroscopic, highly flammable. It is completely soluble in many organic solvents (e.g. chloroform) and in water, with which it forms, in a proportion of approximately 96:4, a minimum azeotrope, which makes it impossible to obtain an ethanol distillation purer than 96. For this reason, “pure alcohol” is defined as 96% ethanol and 4% water approximately. Ethanol (96%) is a mixture comprised of between 95.1 - 96.9% v/v of ethanol and water at 20°C (92.6 - 95.2% m/m). Produced naturally by the fermentation of sugar, it is the most widespread type of alcohol and is the only alcohol suitable for consumption. It is used to make liqueurs and alcoholic beverages. The use of ethanol of agricultural origin for consumption is governed by EC Regulations, as set out in European Regulation 110/2008 Annex I points 1 and 2. Due to its effectiveness as an antiseptic, it is used in the Pharmaceutical Industry as
