Methanol and ethanol mixed together have boiling points 336.5 K and 351.3 K respectively. Which separation technique can be applied?
Answers
Answer:
ethanol and methanol cannot be separated by simple distillation as the difference in their boiling points is less than 25 K. Simple distillation is used when the difference in the boiling points is in the range 25-50 K.
When the difference is less than 25 K, fractional distillation is used.
Additional Information:
Ethanol:- Ethanol is an organic chemical compound It is a simple alcohol with the chemical formula C ₂H ₆O. Its formula can be also written as CH ₃−CH ₂−OH or C ₂H ₅OH, and is often abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor.
Methanol: Methanol, also known as methyl alcohol amongst other names, is a chemical with the formula CH₃OH. It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol. It is a chemical compound.
