obtainable as a white solid C10H18O, called also {Borneo
camphor}, Malay camphor, Malayan camphor, {camphor of
Borneo}, Sumatra camphor, bornyl alcohol, camphol,
and borneol. The isomer from Dryobalanops is
dextrorotatory; the levoratatory form is obtainable from
other species of plants, and the racemic mixture may be
obtained by reduction of camphor. It is used in perfumery,
and for manufacture of its esters. See Borneol.
[1913 Webster +PJC]
