The following table shows the proportion of methanol in some binary mixtures. The only way to completely remove alcohol from a liquid is to boil it away completely or allow it to evaporate until it's dry. by Since we also know that pressure and temperature are directly proportional so water at high pressure will have high boiling point and at low pressure wi. In the case of Ethanol, we would use an op-temp of 130*C. Relative Density : 0.79. For example, ethanol, with a molecular weight (MW) of 46, has a boiling point of 78 C (173 F), whereas propane (MW 44) has a boiling point of 42 C (44 F). Fluids Flow Engineering This type of evaporation can handle larger volumes of solvent and has faster evaporation times for lower boiling point solvents. Baking a recipe containing alcohol resulted in alcohol retention ranging from 25percent (1 hour baking time) to 45 percent (25 minutes, no stirring).
