Completely negative results on the formation of liver glycogen were obtained when the sodium salts of caproic or caprylic acid were fed, as well as after the administration of the ethyl esters of caproic, caprylic, capric, myristic or oleic acids or methyl laurate. Caproic acid was found to be ineffective as a D-glucose-former in the phlorizinized dog. ... 

This is a general method for preparing a-bromo acids. By using exactly analogous directions -bromo- -caproic acid may be obtained in 65-70 per cent yields from w-butylmalonic ester a-bromo-isocaproic acid in 65-70 per cent yields from isobutylmalonic ester and a-bromo-/3-methyl valeric acid in 75-80 per cent yields from sec.-butylmalonic ester.

A gas chromatographic method may be employed for analysis for both benzoic acid and sorbic acid in food, as described in AOAC method 983.16. The acids are extracted from an acidified aqueous homogenized food sample into ether. The acids are then extracted from the ether solution into aqueous alkali, and after acidification they are re-extracted into dichloromethane. Treatment of the residue with N-methyl-N-trimethylsilyltrifluoroacetamide converts the benzoic and sorbic acids into trimethylsilyl esters. These esters are then analyzed with a glass column packed with a support coated with OV-1, in a temperature programmed analysis. Phenylacetic and caproic acids are used as internal standards for benzoic and sorbic acids, respectively. An LC method has also been described for analysis of benzoic acid with simultaneous determination of sorbic acid, and methyl, ethyl, propyl, and butyl p-hydroxybenzoates. The preservatives were extracted from meat or seasonings with 70% ethanol, and analyzed by reversed-phase LC using a Cig stationary phase with a linear gradient from 10 to 70% methanol in 1.5% aqueous ammonium acetate and 1.5% aqueous acetic acid. 

In 1865 Frankland and Duppa reported the synthesis of butyric and caproic esters by the action of sodium, followed by ethyl iodide, on ethyl acetate, mentioning in a footnote that they had become aware of the work of Geuther (see below). They point out that butyric and caproic esters are formed by substitution from acetic ester in the first reaction they supposed that one hydrogen atom in the methyl group of acetic ester was replaced by sodium and in the second reaction two atoms, and that by the action of ethyl iodide the esters of butyric and caproic acids were obtained. In this paper type formulae alone are used, equivalent to ... 

Selectivity of the FPD. The minimum detectable levels of four non-sulfur compounds, methyl anthranilate, pyridine, heptane and caproic acid ethyl ester, on the FPD at a signal/noise ratio of 2 were 368, 784.5, 759.8 and 760 ng, respectively. 

Inhibition of these enzymes is achieved with various diazoacetylamino acid esters, which apparently react with carboxyl groups on the active site, and with pepstatin. The latter is isolated from various Streptomycetes as a peptide mixture with the general formula (R isovaleric or n-caproic acid AHMHA 4-amino-3-hydroxy-6-methyl heptanoic acid) ... 

Important components of hard cheeses (Gouda type) include some carboxylic acid esters (ethyl butanoate, ethyl hexanoate), as well as carboxylic acids (acetic, butyric, isobutyric, valeric, isovaleric, 2-methylbutyric and caproic acids). Cheeses manufactured using bacteria of the genus Propionibacterium (such as Emmental and Gruyere) contain propionic acid and other lower fatty acids, methyl thioacetate, some oxocarboxylic acids, various alcohols, esters (such as ethyl butanoate), lactones (such as 8-decalactone), amines and other basic compounds (also skatole in addition to aliphatic amines), alkylpyrazines (e.g. 2-sec-butyl-3-methoxypyrazine), 4-hydroxy-2,5-dimethyl-2H-furan-3-one (furaneol), 2-ethyl-4-hydroxy-5-methyl-2H-furan-3-one (homofuraneol) and a range of other compounds. 

Palmarosa oil contains free geraniol as its principal constituent together with a small but varying amount of esters of the same alcohol, principally those of acetic and caproic acids. Methyl-heptenone is present in traces, as well as the terpene dipentene. Flatau and Labb claimed to have detected citronellal, but this is denied by Schimmel Co. Else states that farnesol is present in the oil.

Later investigators alcoholyzed imidate salts of other monobasic acids to obtain ortho esters of acetic [13, 14], propionic [15], butyric, valeric, caproic, isocaproic, benzoic [16], and phenylacetic acids [17]. For the latter alcoholysis reactions, the reaction time varies from a few days for the production of methyl orthopropionate to six weeks for ethyl orthobenzoate. McElvain reported that the reaction time is drastically cut by carrying out the reaction in boiling ether [18] or petroleum ether [19]. These conditions provide a reaction temperature below the decomposition point of the imidate salt to the amide.
