| General description: | 1-Pentanol is a linear alcohol. Pentane, a ″next generation″ alcohol fuel, is a promising substitute of conventional gasoline and diesel fuels. Its combustion characteristics have been investigated. Kinetics of thermal decomposition of its isomeric forms (1-pentanol, 2-methyl-1-butanol, and 3-methyl-1-butanol) have been reported. |
