Methanol and Ethanol are similar Chemicals, Methanol has a very sharp scent compared with Ethanol, but this is subjective. Methanol and Ethanol also have different flame colors when burned. Methanol Ethanol light green while the blue, orange, and green.
Methanol when burned to form a light green comes from the hydrolysis process which will form the alkyl compounds, Borax, and this because Borax is also quicker to react with Methanol. At the time of Ethanol burned blue, orange, light green due to ethanol requires a catalyst. The important thing is to Methanol and Ethanol Not for beverage ingredients, but there are people who try to drink, this is one of the most drank Methanol or Ethanol.
Below is a difference according to its structure Chemicals, hopefully you are more definitely set it apart:
Methanol
Molecular formula: CH3OH
Molar mass: 32.04 g / mol
Appearance: colorless liquid
Density: 0.7918 g / cm ³, liquid
Melting point: -97 ° C, -142.9 ° F (176 K)
Boiling point: 64.7 ° C, 148.4 ° F (337.8 K)
Solubility in water: Fully miscible
Acidity (pKa): ~ 15.5
Viscosity: 0:59 mPa • s at 20 ° C
Dipole moment: 1.69 D (gas)
Ethanol
Molecular formula: C2H5OH
Molar mass: 46.07 g / mol
Fluid appearance: colorless
Density: 0.789 g/cm3
Melting point: -114.3
Boiling point: 78.4
Solubility in water: fully mixed
Acidity (pKa): 15.9
Viscosity: 1,200
cP: (20 ° C)
Dipole moment: 1.69
How to distinguish Laing, you provide Salicylates acid and benzoic acid, simply click once. You just provide the following purposes:
1. Prepare two test tubes, tubes A and B
2. In both tubes A and B enter liquid suspected of Ethanol and Methanol to tube A to tube B
3. In tube A add acid Salicylates, close the tube with cotton water condition
4. In tube B add Acid Benzoate, close the tube with cotton that has been filled with water
5. Heat water in a glass large enough.
6. Insert the tube A and tube B into the already filled glass of water that is heated again. REMEMBER. INTO THE GLASS! DO NOT DIRECT DIPANASIN, because if DIPANASIN DIRECT FIRE CAN.
7. Wait up to 5 minutes.
8. Open cotton from each tube,
9. Breathe in the smell of cotton (not too long inhaled, lead to drunkenness)
Tube "A" Ethanol = smell like Banana Ambon
Tube "B" Methanol = smell like oil wind.
