A simple gas chromatography–flame ionisation method was initially developed for the simultaneous determination of the prohibited flavours, namely diethylene glycol (DEG), diethylene glycol monoethyl ether (DEGME) and coumarin in food samples. The analytes were extracted using methanol, and was ...

Densities and viscosities were measured as a function of composition for binary liquid mixture of diethylene glycol monoethyl ether [CH3CH2O(CH2)2O(CH2)2OH] + water from 293.15 to 333.15 K at atmospheric pressure, with a capillary pycnometer and Ubbelohde capillary viscometer respectively. From ...

The synthetic method is used for the determination of the liquid phase solubility of methane in 1-octanol at three temperatures (273.25, 283.15, and 293.2) K and of methane in n-dodecane at 273.1 K at pressures up to about 10 MPa. The new gas solubility data is applied to evaluate the molality s...

Penicillium camemberti is a technologically relevant fungus used to manufacture mold-ripened cheeses. This fungal species produces many volatile organic compounds (VOCs) including ammonia, methyl-ketones, alcohols and esters. Although it is now well known that VOCs can act as signaling molecules...

New routes for transforming biomass-derived glycols into value-added products through innovative catalytic processes are of great relevance in the chemical industry. The etherification of these glycols with alkyl alcohols is a process to produce oxygenated fuel additives, antimicrobial and antis...

Equilibrium data for the water + 1-butanol + 2-octanol system is determined in this work. Liquid-liquid equilibrium (LLE) data are obtained at 303.15 K and 313.15 K, with a view to investigating the influence of temperature.Vapour-liquid-liquid equilibrium (VLLE) and vapour-liquid equilibrium (V...

A polymer inclusion membrane (PIM) that contains a polyvinyl chloride (PVC) polymer matrix and 1-octanol (OCT) as specific carrier (PO-PIM) was prepared to investigate the mass transfer behaviour of phenol in aqueous solutions. Results showed that the mass transfer behaviour of the PO-PIM for phe...

We have studied for the first time the thermodynamic behavior of the well-established antimicrobial drug – dioxidine (2,3-dihydroxymethylquinoxaline-1,4-dioxide) in water and the water/1-octanol biphasic system. Enthalpies of solution and solubility of dioxidine were experimentally determined a...

Protective agents based on tetraethoxysilane (TEOS) have been widely used for the protection of stone heritages. However, TEOS-based protective agents suffer from practical drawbacks, such as crack formation of the gel during the drying phase due to the developed capillary force, which is typica...

Recovery of levulinic acid from an aqueous solution using a tertiary amine, tri-n-octylamine (TOA), as an extractant in methyl isobutyl ketone (MIBK) was studied at different temperatures (293–333 K). The physical equilibrium studies were performed using MIBK as a diluent. Partition (P) and dim...

Processes of adsorption and desorption of a model active substance (octylamine) on the surface of unmodified titanium dioxide (E 171) have been performed. The effects of concentration of octylamine and time of the process on the character of adsorption have been studied and the efficiency of the...

A detailed study of 3-hydroxypropionic acid (3-HP) reactive extraction with tri-n-octylamine (TOA) is proposed for the first time. It aims at uncovering some solvent-solutes interactions and providing global mechanisms to better understand and design the reactive liquid-liquid extraction of 3-HP...

An automated salting-out assisted liquid-liquid microextraction (SALLME) procedure based on a flow system was developed as new approach for pretreatment of complex sample matrix. In this procedure 1-octylamine was investigated as novel extractant for the SALLME. The procedure involved aspiration...

In this study, Octylamine (OA) capped zinc oxide (ZnO) nanoparticles were synthesized by the wet - chemical method. Zinc acetate dihydrate was used as precursor materials. The structural, morphological and optical properties were characterized by X-ray Diffraction (XRD), High resolution-Scanning...

Since last 50 years, the malonic acid is produced from petroleum feedstock while recently a patent is filed by Lygos, Inc., a lab in Berkeley, California to produce malonic acid through genetically natural yeast cells by biological fermentation. Like all fermentation process the proposed method ...

Magnetic particles were successfully synthesised by a new and simple one-step auto-ignition method, with octylamine as organic fuel and iron nitrate nonahydrate as an oxidant, both in an aqueous solution. After synthesis and stabilising at 550 °C in reduced atmosphere, the samples consisted of ...

The densities, kinematic viscosities and other derived properties of the binary systems n-heptane+1-chlorooctane and methyl butanoate+1-chlorooctane were determined at 283.15, 293.15, 303.15 and 313.15 K and atmospheric pressure for the whole composition range. Moreover, similar properties were ...

Ignition delay times were measured behind reflected shock waves under highly dilute conditions (99% Ar) for 10 ternary blends of methyl octanoate, n-nonane, and methylcyclohexane (MCH), using a Design of Experiments approach, namely an L9 array.
