Characteristics of Methanol
1.Methanol is the simplest alcohol, and is a light, volatile, colorless, flammable, liquid with a distinctive odor that is very similar to but slightly sweeter than ethanol (drinking alcohol).
2.At room temperature it is a polar liquid and is used as an antifreeze, solvent, fuel, and as a denaturant for ethanol.
3.It is also used for producing biodiesel via transesterification reaction.
