2-Octanone is an eight carbon ketone that is usually made from the oxidation of 2-octanol. It is a mobile, oily liquid with a pungent odor that can be unpleasant at high concentrations.
Contents
Properties
Chemical
2-Octanone will burn in air to release carbon dioxide and water vapor.
Physical
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.[1]
Availability
2-Octanone is only available from the major chemical suppliers and some specialty aroma compound companies.
Preparation
The simplest method of preparing 2-octanol is by the Jones oxidation of 2-octanol.
(explanation of procedure will be posted here soon -zts16)
Another method involves distilling sodium ricinoleate, obtained from castor oil, with sodium hydroxide.[2]
Projects
- Haloform as a route to heptanoic acid
- Aroma compound collection
Handling
Safety
2-Octanone is not hazardous to handle, although it has a very strong odor that can be unpleasant to have on the skin.
Storage
There are no special storage precautions.
Disposal
Spills of 2-octanone and glassware that has been used with it can be cleaned up easily using isopropanol, acetone, or a mixture of both. Afterwards it can be successfully mopped up with water.
