1. properties
achromatic oil-state liquid.
boiling point: 176°c.
crystal when frozen. freexing point higher than 1°c.
slightly resolvable in water 0.4%-0.6%. resolvable in propanediol. mutually resolvable with ethanol and oil.
2. extract methol
fractionated from some essence oil containing rich 1,8-cineole (with fraction range 170-180°c). for example, eucalyptus globulus oil, containing about 60% 1,8-cineole, can be fractionated from and then be seperated from to get the 1,8-cineole.
