2-Octanone will burn in air to release carbon dioxide and water vapor.
2-Octanone is a clear, colorless liquid. It is oily and barely soluble in water (0.899 g/L at 20 °C), although it will form emulsions. It is however soluble in alcohols and ether It has a strong odor which is reminiscent of fruity candy and blue (green) cheese, sometimes described as unripe apple.
2-Octanone is only available from the major chemical suppliers and some specialty aroma compound companies.
The simplest method of preparing 2-octanol is by the Jones oxidation of 2-octanol.

2-Octanone is not hazardous to handle, although it has a very strong odor that can be unpleasant to have on the skin.
There are no special storage precautions.
Complete neutralization can be done with an oxidizing mixture, like Fenton's reagent, by adding it in small amounts. Since it's not very flammable, it should be mixed with a more flammable solvent, like ethanol or acetone before burning it outside or in an incinerator.
