Kiliani's classic reduction of α-glucoheptonic (D-gluco-D-guloheptonic) lactone led to small, variable yields of n-heptanoic acid and varying amounts of the lactone of a hydroxy-n-heptanoic acid. A repetition of this work showed that the combined yields of these two products reached a maximum near 70% of theory when the reduction with constant-boiling

Decarbonylation of heptanoic acid over carbon-supported platinum nanoparticles
Green Chem., 2014The decarbonylation and decarboxylation of heptanoic acid over carbon-supported Pt nanoparticles were studied in a continuous flow fixed bed reactor at 573 K and 37 bar for liquid-phase operation and 1 bar for gas-phase operation. Under liquid-phase conditions, the TOF over Pt supported on Norit carbon was 0.0052 s−1 and independent of Pt loading.

Growth and Polymer Incorporation of Pseudomonas oleovorans on Alkyl Esters of Heptanoic Acid
Macromolecules, 1994Heptanoic acid and its methyl, ethyl and propyl esters were used as substrates in order to determine the growth behavior of P. oleovorans on these substrates. It was found that the cell densities reached during the fermentations depended strongly on the substrates concentrations.

The consequence of mixing an alkanoic acid with an alkylamine is a proton transfer between the acid and the amine leading to a complexation, which is dependent on the mixing ratio between the two components. If water is added, the formed ammonium alkanoate will have surfactant properties.

Journal of Chemical & Engineering Data, 2004
Vapor pressure data were measured for the following carboxylic acids: propionic, butyric, isobutyric, valeric, isovaleric, hexanoic, and heptanoic acids. The pressure ranged between ∼5 kPa and atmospheric pressure (at sea level), and the corresponding temperatures were between 85 and 180 °C, depending on the acid being measured.

Simple polyol route to synthesize heptanoic acid coated magnetite (Fe3O4) nanoparticles
Materials Research Bulletin, 2013Abstract Magnetite (Fe3O4) nanoparticles were prepared via polyol method by using FeCl2 as only source of iron. As-prepared samples were characterized by powder X-ray diffractometer (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analyzer (TGA) and vibrating sample magnetometer (VSM ...

Extraction of manganese(II) from ammonium chloride solutions with heptanoic acid
Hydrometallurgy, 1989Abstract The distribution of Mn(II) between aqueous 1.0 M NH4Cl solution and heptanoic acid solutions in carbon tetrachloride was studied. Regression analysis methods were used to determine the species present in the organic phase. It has been established that the composition of these species depends on the total manganese(II) concentration in the ...
