Properties
Chemical
Octyl acetate can hydrolyze to 1-octanol and acetic acid. It can also act as a solvent.
Physical
Octyl acetate is insoluble in water but soluble in ethanol, 1-octanol and diethyl ether. It has a fruity smell. Octyl acetate has a wide liquid range. It melts at -38 °C and boils at 211 °C.
Availability
Octyl acetate may be extracted from oranges or grapefruits.
Preparation
As octyl acetate is an ester of 1-octanol and acetic acid, it can be synthesized by adding the two together in dehydrating conditions, though this is difficult.
Projects
- Extract octyl acetate from oranges or grapefruits
- Fragrant compound collecting
Handling
Safety
Octyl acetate is not particularly toxic, but do not ingest lab-grade material.
Storage
Should be stored in glass closed bottles, away from any flame source.
Disposal
Octyl acetate should be mixed with a more flammable solvent and safely burned.
