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.

Pentanol is one of the promising "next generation" alcohol fuels with high energy density and low hygroscopicity. In the present work, dominant reaction channels of thermal decomposition of three isomers of pentanol: 1-pentanol, 2-methyl-1-butanol, and 3-methyl-1-butanol were investigated by CBS-QB3
