Methanol is CH3OH while ethanol is C2H5OH. The difference is CH2.
To avoid misuse of ethanol for drinking purpose it is denatured with methanol.
Generally the composition is 10 % methanol and 90 % ethanol.
Not very good in methanol and ethanol.
ethanol or methanol
I think alcohol is the general name of the family of: methanol, ethanol, propanol...
Methanol have single carbon atom compound and ethanol have two carbon atoms.
Methanol is CH3OH, ethanol is CH3CH2OH. Both are alcohols, ethanol has one carbon more (or a CH2 group more) and is less polar than methanol. Also ethanol has higher boiling point than methanol.
To avoid misuse of ethanol for drinking purpose it is denatured with methanol.
You can drink ethanol. If you drink methanol, even a small amount, you will go blind.
Methanol
Methanol and ethanol mix together well in part because they both have a low boiling point. Methanol and ethanol mixed together also metabolizes well.
ethanol is used in alcohol
By fractional distillation, methanol boils at about 61 Celsius while ethanol at 78.5 Celsius.
Methanol isn't actually poisonous, but the chemicals produced when your body metabolises methanol are. The enzymes that metabolise methanol also metabolise ethanol, but when both are present the ethanol is processed first. Methanol is also removed from the body via the lungs, sweat glands and in urine. Giving ethanol prevents the toxic by products of metabolism whilst these other methods remove the methanol from their system. This treatment only works if given early. It does not reverse the the damage done by methanol that has already been metabolised.
bastet
Alcohols such as methanol, ethanol, propanol, butanol etc can have hydrogen bonds.
Methanol has a Boiling point under standard conditions of 64.7 °C, and ethanol of 78.4 °C. You I can boil off vapor and collect Methanol and Ethanol, and use that cooled back down to liquid form and preform a test.
