It is miscible with a number of organic solvents. n-Butanol is soluble in water and it forms azeotropic solution with it (42% H2O by mass, bp 92.7°C). n-Butyl alcohol is a typical aliphatic alcohol. The n-butanol vapour has an irritant effect on mucous membranes and narcotic effect in higher concentration
