The objective of this study was to evaluate the antimicrobial effects of benzoic and sorbic acid salt and their nano-solubilisates against planktonic and biofilm cultures of Staphylococcus aureus, Pseudomonas fluorescens and chicken microbiota. The antimicrobial activity was affected by the part...

Preservation of emulsions relies on factors including pH, temperature, structure and the application of carboxylic acid preservatives, such as sorbic and benzoic acid. Organic acid preservatives tend to migrate to the lipid phase of emulsions. Taking into account the fact that organic acid in th...

This research reports a pressure dependent Raman study of the sorbic acid between 0.0 and 10.0 GPa. The unpolarized Raman spectra were measured in the spectral range of 20–3000 cm− 1. The high-pressure Raman scattering study of the sorbic acid showed that it underwent a gradual, disordering pro...

A shock tube study of the autoignition of methyl decanoate, a candidate surrogate for biodiesel fuels containing large methyl esters, has been carried out. Ignition delay times were measured in reflected-shock-heated gases by monitoring electronically-excited OH chemiluminescence and pressure. M...

The thermal decomposition of methyl decanoate (MD) was studied in a bench-scale pyrolysis set-up equipped with a dedicated on-line analysis section including a GC × GC-FID/(TOF-MS). This analysis section enables quantitative and qualitative on-line analyses of the entire reactor effluent with h...

A detailed kinetic model for the oxidation of the biodiesel surrogate, methyl decanoate, has been developed and tested against a broad range of experimental data. The methyl decanoate model consists of both low and high temperature oxidation chemistry. It has been constructed strictly through th...

The production of methyl decanoate (MeDC) through esterification of decanoic acid (DeC) with methanol by reactive distillation is operationally challenging and energy-intensive due to the complicated behaviour of the reaction system and the difficulty of retaining the reactants together in the r...

The pyrolysis of methyl decanoate (MD), an ideal surrogate of biodiesels, was investigated in a flow reactor at the pressures of 30 and 760 Torr and the temperature ranging from 773 to 1198 K. A great variety of pyrolysis products including free radicals, n-alkanes, 1-alkenes, alkynes, unsaturat...

Ignition delay times were measured in a constant volume spray combustion chamber for four compounds considered as surrogates for fatty-acid methyl/ethyl ester biodiesel fuels. Experiments were performed for methyl decanoate, ethyl nonanoate, methyl 9-decenoate, and methyl 5-decenoate for charact...

Laminar flame speeds and Markstein lengths of methyl decanoate (MD)-air mixtures were measured within a range of equivalence ratio at different elevated pressures and temperatures using outwardly propagating spherical flames developed inside a constant volume combustion chamber. Shadowgraph tech...

New experimental densities and viscosities data for binary mixtures of methyl decanoate plus n-heptane were reported at temperatures of (298.15, 308.15 and 318.15) K and pressures of (0.1–15) MPa. The expanded uncertainty for density measurement is estimated to be 2 kg m−3 and the relative expa...

This paper aims to improve a knowledge base of methyl decanoate, a long alkyl-chain biodiesel surrogate fuel gaining popularity in engine combustion research. To this end, a comparative study on diesel and methyl decanoate combustion has been conducted with a focus on high temperature flame stru...

Major efforts in the search for techniques for the development of reduced kinetic mechanisms for biodiesel have been observed, since these mechanisms may have thousands of species. This paper proposes a reduction strategy and presents the development of a reduced kinetic mechanism for piloted je...

In this work, the isobaric molar heat capacities of methyl caprate, methyl laurate and their mixtures at temperatures from 313 K to 335 K and at pressures up to 16.2 MPa were measured using a flow calorimeter. The isobaric molar heat capacities of these mixtures were observed to increase as the ...

In this work, we measured the isobaric vapor-liquid equilibrium (VLE) data for the binary system of methyl caprate (1) + methyl laurate (2) at 2,4 and 6 kPa with a modified Othmer still. The point consistency test of Van Ness test method was applied to check the thermodynamic consistency of all ...

Densities and kinematic viscosities of binary mixtures for ethyl caprate with 1-propanol, 1-butanol, and 1-pentanol were measured at temperatures from 283.15 K to 318.15 K and at ambient pressure (0.1 MPa) over the entire composition range. Excess molar volumes and viscosity deviations of the mi...

Partition coefficients for compounds (solutes) from water to isopropyl myristate, IPM, have been obtained from the literature, either as directly determined partition coefficients or from solubilities in water and in IPM. The general solvation equation of Abraham has been applied to 141 such par...

Cafestol and kahweol (C&K), two coffee diterpene alcohols with structural similarity which exhibit anticarcinogenic effects, were isolated from green coffee Arabica beans, followed by their lipase-catalysed esterification and purification by preparative high-performance liquid chromatography (HP...

Two types of Animal Fatty Wastewater Sludges (AFWS 1 and 2) were analyzed and fully characterized to determine their suitability for conversion into biofuel. AFWS 1 was determined to be unsuitable as it contains 68.8 wt.% water and only 32.3 wt.% dry material, of which only around 80% is lipids ...

Sea buckthorn (Hippophae rhamnoides L.) pulp oils (SPOs) are rich in a variety of beneficial bioactive ingredients. Nevertheless, SPOs would be exposed to plastic equipment during processing, resulted in increasing phthalates contents and edible risk, as well as affecting oil quality. For these ...
