N - Butanol

N - Butanol About

N-Butanol (CHO) is a straight-chain primary alcohol belonging to the family of higher alcohols. It is a colorless, flammable liquid with a mild alcoholic odor and moderate evaporation rate. It is produced industrially through processes such as the oxo process (hydroformylation of propylene) or fermentation (bio-butanol).

It has balanced polarity, making it an excellent intermediate solventmore hydrophobic than ethanol but still miscible with many organic solvents. This unique property allows it to dissolve both polar and non-polar substances, making it highly valuable across multiple industries.
