1-Octyne (7.5 g) and formic acid (100 mL) were heated in an oil bath at 100 ºC until all starting material was consumed. The progress of the reaction was monitored by GC analysis of the reaction solution. Quantitative GC analysis at the end of the reaction (6 h) indicated 92% yield of 2-octanone. The cooled reaction mixture was taken up with CH2Cl2 (170 mL), and the solution was washed with water, sodium carbonate solution, and water, dried over MgSO4, and evaporated in vacuo. The residue was distilled (bp 171–173 ºC) to give 2-octanone (7.42 g, 85%).

2-Octanone has a floral and bitter, green, fruity (unripe apple) odor
with a bitter camphoraceous taste. May be synthesized by the
oxidation of methyl hexyl carbinol with K2Cr2O7 and sulfuric acid;
also by oxidation of 2-octanol over zinc oxide at 330 - 340°C. | [Chemical Properties]
2-Octanone has a floral and bitter, green, fruity (unripe apple) odor and bitter, camphoraceous taste. | [Chemical Properties]
Colorless liquid; pleasant odor; cam-phor taste. Insoluble in water; solublein alcohol, hydrocarbons, ether, esters, etc. Com-bustible. | [Occurrence]

ChEBI: A methyl ketone that is octane substituted by an oxo group at position 2. | [Preparation]
By oxidation of methyl hexyl carbinol with K2Cr2O7 and sulfuric acid; also by oxidation of 2-octanol over zinc oxide at
330 to 340°C. | [Production Methods]
2-Octanone can be produced by oxidation of methyl hexyl
carbinol, 2-octanol, or 1-octene or by reductive condensation
of acetone with pentanol. Commercial samples can have a
purity of 98%. | [Aroma threshold values]

2-Octanone is a volatile flavor compound reported to be found in blue cheese, acerola fruit, blue crab and cray fish. | [Industrial uses]
Methyl n-hexyl ketone is used as solvent for vinyl compounds and dyes and is
suitable for dispersing dyes in light-weight petroleum oils for newsprint inks. | [Toxics Screening Level]
The initial threshold screening level (ITSL) for 2-octanon~ (also known as methyl hexyl ketone) is being established at 7 μg/m3 based on an annual averaging time. |
