propanoln.

Brit.

/ˈprəʊpənɒl/, U.S.

/ˈproʊpəˌnɔl/,

/ˈproʊpəˌnɑl/

Origin: A borrowing from German. Etymon: German Propanol.

Etymology: < German Propanol (1893 in the passage translated in quot. 1894¹) < Propan propane n. + -ol -ol suffix. Compare Spanish propanol (1893 or earlier).

Chemistry.

Either of two isomeric liquid alcohols, used as solvents: (a) the primary alcohol CH₃CH₂CH₂OH (also n-propanol, 1-propanol; also called propyl alcohol); (b) the secondary alcohol CH₃CH(OH)CH₃ (also 2-propanol; also called isopropanol, isopropyl alcohol). See also propyl alcohol n. at propyl n. Compounds.
