Due to having only a single carbon atom attached, this compound is classified as an alcohol which serves as its primary alcohol type and an isomer made up of propanol; furthermore, it occurs naturally through fermentation processes in very minute amounts.

The molecular mass is 60.09 grams per mole. Additionally, this uncolored liquid features an alcohol-like scent with mild undertones that make for effective usage as pharmaceutical manufacturing solutions and fuel engine applications due to its high octane count.

What is 2 Propanol?

2 propanol (C3H8O), commonly referred to as isopropyl alcohol and with its chemical formula C3H8O is an organic compound composed of carbon, hydrogen and oxygen atoms that ignites easily when mixed together in combustion reactions.

Furthermore, it has an unpleasant odour due to a bonding between its hydroxyl component and carbon chain’s middle carbon atom; hence making this compound secondary alcohol, in addition to being structurally similar to one propanol.

Additionally, it can be mixed with water chloroform ether and ethanol and its viscosity increases significantly at lower temperatures; when exposed to oxygen it may even undergo oxidation to form Acetone.

Two propanol is produced primarily through indirect hydration; when propene is combined with sulfuric acid it forms an ester mixture; hydrolysis then yields isopropyl alcohol as the final product.
