1 Butanol is a compound called an alcohol. This is because of a hydrogen atom of a carbon compound is replaced by an -OH group. From butane we get butanol. Alcohols formed from alkanes are called alkanols and have the general formula CnH2n+1OH. Butanol is a liquid at room temperature because of the hydrogen bonding that has strong intermolecular forces so allows butanol to have a much higher boiling point. Butanol is made from the fermentation of corn.
Physical and chemical properties: Like all alcohols, 1 Butanol has a few different names, scientific or common. They are n-butyl alcohol, propyl carbinol and butanol.
Chemical formula: C4H9OH or CH3(CH2)3OH or C4H10O Structural formula: -C-C-C-C-OH Melting point: -89.5 ÃÂ°C Boiling point: 117.3 ÃÂ°C (high boiling point because there is a large number of carbon atoms) Molecular weight: 74.1 g Density: 0.8098 g / cm3 Solubility: 8ml / 100ml water at 25ÃÂ°C (because of oxygen it is quite polar) Soluble in water, miscible with alcohol and ether Vapour density: (Air=1), 2.6
