General description

1-Pentanol is a linear alcohol. Pentane, a ″next generation″ alcohol fuel, is a promising substitute for conventional gasoline and diesel fuels. Kinetics of thermal decomposition of its isomeric forms (1-pentanol, 2-methyl-1-butanol, and 3-methyl-1-butanol) have been reported.
1-Pentanol is a colorless liquid having a pleasant odor, which can be obtained as a product from the process of fractional distillation of mixed alcohols resulting from the chlorination and alkaline hydrolysis of pentane occurs.

Application

1-Pentanol may be used as a cosurfactant in the water-in-oil mixed surfactant microemulsions.
