The letter n may be used in front of butane in order to differentiate the normal butane from its isomer.

Examples

  • It is a liquid, smelling like fusel oil and boiling at 108. 4° C. Methyl ethyl carbinol, C._3·C.2H_5·C.OH, is the secondary alcohol derived from n-butane.

  • Note the 30\% propane with n-butane does better in cold weather than the 20\% propane in n-butane (Gaz brand).

  • At 60 degrees, it is 88\% n-butane when half full, and 97\% n-butane when 1 / 4 full.

    undefined

  • Coleman and Optimus fuel (70\% n-butane, 30\% propane)

    undefined

  • At 35 degrees, the Gaz canister is 95\% n-butane at half full and 99\% n-butane at 1 / 4 full.

    undefined

  • The blends do mix, and even below the boiling point of the high boiler present (n-butane for example) there will be butane boiled off, just not as much as at higher temperatures. mole fraction in vapor = mole fraction in liquid x vapor pressure
