Benzylammonium heptanoate–heptanoic acid (1/1) [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2013
The title salt, C7H10N(+)·C7H13O2(-)·C7H14O2, is an unusual 2:1 stoichiometric combination of two carb-oxy-lic acid mol-ecules and one amine. Although there are crystal structures of a number of 1:1 complexes reported in the literature, 2:1 acid amine complexes are rather uncommon.

Impact of Drying Method on the Evaluation of Fatty Acids and Their Derived Volatile Compounds in ‘Thompson Seedless’ Raisins

open access: yesMolecules, 2020
Air- and sun-dried raisins from Thompson Seedless (TS) grapes were analyzed under GC/MS to evaluate fatty acids (FAs) and their derived volatile compounds, coming from unsaturated fatty acids oxidation.

Using in situ GC-MS for analysis of C2–C7 volatile organic acids in ambient air of a boreal forest site [PDF]

open access: yesAtmospheric Measurement Techniques, 2017
An in situ method for studying gas-phase C2–C7 monocarboxylic volatile organic acids (VOAs) in ambient air was developed and evaluated. Samples were collected directly into the cold trap of the thermal desorption unit (TD) and analysed in situ ...

The gut microbiome promotes arsenic metabolism and alleviates the metabolic disorder for their mammal host under arsenic exposure

open access: yesEnvironment International, 2023
Gut microbiome can participate in arsenic metabolism. However, its efficacy in the host under arsenic stress is still controversial. To clarify their roles in fecal arsenic excretion, tissue arsenic accumulation, host physiological states and metabolism,

Transforming micropores to mesopores by heat cycling KOH activated petcoke for improved kinetics of adsorption of naphthenic acids

open access: yesHeliyon, 2023
Formation of activated carbon from petroleum coke by KOH, results in high specific surface area materials that are predominantly microporous. This initial microporosity means that the adsorption kinetics of target species are not as rapid as they could ...

Determination of the Fatty Acids in Beer by SPME.

open access: yesKvasný průmysl, 2005
An escalated content of fatty acids during fermentation can influence the quality of final beer. So it is necessary to use the suitable analytical method for the determination of their concentrations in beer or hopped wort.

Interactions in the Thallium(I) Heptanoate and Heptanoic Acid System: Association, Aggregation, and Phase Behavior

open access: yesJournal of Colloid and Interface Science, 1997
The phase, association, and aggregation behavior of the binary system [TlO2C(CH2)5CH3 + HO2C(CH2)5CH3] have been investigated through temperature and enthalpy vs composition diagrams by determination of the thermal behavior of the pure components and 30 mixtures over an interval of nearly 300 K, and by differential scanning calorimetry and polarized ...
