| Questions And Answer | Back Directory | [Synthesis]
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 is a kind of natural ketone found in many sources such as coco, baked peanuts, potato, cheese, beer, banana and oranges. It can be used as a flavor and fragrance ingredient. It is used in the field of fiber, medicine, pesticides and spices for the synthesis of fiber oil, defoamer and the preparation of surfactants, coal flotation agent.

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]
