Simple polyol route to synthesize heptanoic acid coated magnetite (Fe3O4) nanoparticles

Materials Research Bulletin, 2013
Abstract 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, 1989
Abstract 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 ...

Stability of a Surface Adlayer at Elevated Temperature:  Coronene and Heptanoic Acid on Au(111)

The Journal of Physical Chemistry C, 2008
The temperature dependence of the stability of the adlayer formed at the interface between Au(111) and a coronene-heptanoic acid solution is reported. At coronene concentrations above 1.5 x 10 -4 M and at 21 °C, a dense coronene adlayer is observed.

Differential effects of heptanoate and hexanoate on myocardial citric acid cycle intermediates following ischemia-reperfusion

Journal of Applied Physiology, 2006
In the normal heart, there is loss of citric acid cycle (CAC) intermediates that is matched by the entry of intermediates from outside the cycle, a process termed anaplerosis. Previous in vitro studies suggest that supplementation with anaplerotic substrates improves cardiac function during myocardial ischemia and/or reperfusion.

A practical synthesis of 3(S)-methyl-heptanoic acid from (S)-citronellol

Tetrahedron: Asymmetry, 1996
Abstract Chiral 3-methyl-heptanoic acid is readily accessible by functional group manipulation of optically active citronellol. In principle, this approach is general and could be applied to the synthesis of chiral 3-methyl-alkanoic acids seven carbon atoms in length and longer.

Influence of Sn Promoter on Pd and Pt Catalysts for the Conversion of Heptanoic Acid and Propane

2018
Silica-supported Pd catalysts can be used to selectively remove oxygen from biomass-derived carboxylic acids through decarbonylation. This work aims to improve Pd catalyst stability and selectivity towards desirable products by varying metal particle size as well as by introducing Sn to the catalyst. Catalysts were prepared by ion exchange or incipient

Utilization of semi continuos catalitic reactive distillation process in the esterification of heptanoic acid

2010
El Heptanoato de etilo es preparado por esterificaci´on directa del ´acido heptanoico con etanol en presencia del ´acido sulf´urico como catalizador. El proceso de destilaci´on semi continuo catal´ıtico reactivo (reactor extractor unido a una columna de tipo dean stark) fue utilizado como una alternativa en el proceso de esterificaci´on.
