| | 2-Octanone Usage And Synthesis |
| 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%).

Chem. 1991, 56, 2912–2914. | | Description | 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.

| | Description | 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 | Colorless liquid; pleasant odor; cam-phor taste. Insoluble in water; solublein alcohol, hydrocarbons, ether, esters, etc. Com-bustible. | | Chemical Properties | 2-Octanone has a floral and bitter, green, fruity (unripe apple) odor and bitter, camphoraceous taste. | | Occurrence | Reported found in apple, apricot, banana, cranberry, grape, raisin, papaya, peach, raspberry, strawberry, leek,
peas, clove, wheat bread, many cheeses, butter, milk, cooked egg, yogurt, caviar, fatty fish, meats, beer, hop oil beer, cognac, rum,

clam, truffle, maté and mastic gum oil. | | Uses | Perfumes, high-boiling solvent, especiallyfor epoxy resin coatings, leather finishes, flavor-ing, odorant, antiblushing agent for nitrocelluloselacquers. | | Uses | 2-Octanone is used in perfumes, high-boiling solvent, especially for epoxy resin coatings and in leather finishes. It is used in flavoring, odorant. It can act as antiblushing agent for nitrocellulose lacquers. | | Uses | 2-Octanone may be used as an analytical reference standard for the quantification of the analyte in sugar-cane spirits and rum samples and whey protein concentrate using chromatography based techniques. | | 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%. | | Preparation | By oxidation of methyl hexyl carbinol with K2Cr2O7 and sulfuric acid; also by oxidation of 2-octanol over zinc oxide at
