Ethyl octanoate

The spreading of smells through still air is due to the diffusion of the gas molecules. In a room that is 5 m long, a vial of ethyl octanoate is opened at the north end of the room, and simultaneously a second vial containing p-anisaldehyde is opened at the south end of the room (5 m away). Ethyl octanoate (C10H20O2) has a fruity smell, and p-anisaldehyde (CgHsO,) has a minty smell. How far (in meters) from the north end of the room must a person stand to smell first a minty smell ...

In another investigation, the volatile compounds were isolated [19] using a Porapack Q trap by vacuum for 2 h and were then eluted with hexane. The esters were the chemical class of compounds that predominated in the samples among 21 volatile compounds detected. Ethyl butanoate, ethyl 2-methylbutano-ate, 1-butanol, ethyl hexanoate, 3-hydroxy-2-butanone, ethyl octanoate, acetic acid, linalool, palmitic acid, and oleic acid were identified in cupuacu pulp by solid-phase extracton [15]. 

Add each to an aqueous solution of sodium bicarbonate, NaHCC>3. Only the octanoic acid will react with this solution. It will dissolve in aqueous NaHC03 as a water-soluble salt with the evolution of carbon dioxide. There will be no reaction with ethyl octanoate.

Ethyl hexanoate and octanoate were the predominant FA esters found in Tinta Negra wines, whereas diethyl succinate and ethyl lactate were the most abundant diprotic acid ethyl esters. According to the authors, the most sensory important flavors seem to be attributed to 3-methylbutan-l-ol, 2-phenylethanol, isoamyl acetate, diethyl succinate, 2-phenylethylace-tate, phenylacetaldehyde, y-nonalactone, ethyl hexanoate, ethyl octanoate, hexanoic acid, and octanoic acid. 

The products of lipid oxidation in monolayers were also studied. Wu and coworkers (41) concluded that epoxides rather than hydroperoxides might be the major intermediates in the oxidation of unsaturated fatty acids adsorbed on silica, presumably because of the proximity of the substrate chains on the silica surface. In our work with ethyl oleate, linoleate and linolenate which were thermally oxidized on silica, the major decomposition products found were those typical of hydroperoxide decomposition (39). However, the decomposition patterns in monolayers were simpler and quantitatively different from those of bulk samples. For example, bulk samples produced significantly more ethyl octanoate than those of silica, whereas silica samples produced more ethyl 9-oxononanoate than those of bulk. This trend was consistent regardless of temperature, heating period or degree of oxidation. The fact that the same pattern of volatiles was found at both 60°C and 180°C implies that the same mode of decomposition occurs over this temperature range.
