Selective hydrogenolysis of biomass-derived furfuryl alcohol (FFA) to 1,5- and 1,2-pentanediol (PeD) was conducted over Cu-LaCoO3 catalysts with different Cu loadings; the catalysts were derived from perovskite structures prepared by a one-step citrate complexing method. The catalytic performanc...

A biorefinery strategy for the coproduction of ethanol and 1,5-pentanediol (1,5-PDO), which can be used as polyester and polyurethane component, from lignocellulosic biomass is proposed. This strategy integrates biomass fractionation with simultaneous conversion of hemicellulose and cellulose co...

Low-speed rotation of disc in an internal circulation of a novel de-emulsification with rotation-dise horizental contactor (RHC-D) realized de-emulsification for O/W emulsions due to repeated coalescence in oil-wet narrow channels at a low rotation speed. For three emulsions included ethanol/wat...

New experimental density data for binary mixtures of (di-isopropyl ether + 1-hexanol) over the composition range are reported, between 293.15 and 393.15 K, and for pressures from 0.1 MPa up to 140 MPa. To perform these measurements, a vibrating tube densitometer, calibrated with an uncertainty o...

In this study, the vapor-liquid equilibrium data for of six binary pairs made up from 1-hexanol, 1-heptanol, 1-nonanol and 1,3-propanediol at P = 101.3 kPa are presented. Differential scanning calorimetry (DSC) was used to obtain the equilibrium data for each pair binary system. The experimental...

The kinetics of the liquid-phase etherification of 1-hexanol to di-n-ethyl ether and water on the ion-exchange resin Amberlyst 70 in the temperature range 423–463 K is studied. The strong inhibition effect of water is considered following two approaches. First, a model stemming from a Langmuir–...

The solubility of light fullerenes (C60 and C70) in 1-hexanol was investigated in the range of pressures of 0.1–100 MPa and in the range of temperatures of 298.15–363.15 K. In all of the studied temperatures, solubility increases monotonously with increasing pressure. At ambient pressure, we h...

In this work, 2-ethyl-1-hexanol, a long chain alcohol, is used to extract pentavalent vanadium V(V) from both sodium metavanadate solution and a synthetic leach liquor. At first, effects of process parameters on the extraction of V(V) from a solution free from the other metals are examined and d...

Liquid-liquid equilibrium (LLE) data for {water + 5-hydroxymethylfurfural (HMF) + 1-pentanol/1-hexanol/1-heptanol} ternary systems was measured at 298.15 K and 0.1 MPa. The solute selectivity and the capacity of alcohols were evaluated and the results showed that 1-pentanol has better performanc...

The knowledge of the liquid-liquid phase equilibrium and the corresponding interfacial properties of quaternary liquid mixtures can be used for the optimization of extraction processes relevant for industrial application. The purpose of this work is the theoretical prediction of the above mentio...

Association of 1-hexanol in n-hexane has been studied by measurements of nonlinear dielectric effect (NDE) and near-infrared (NIR) spectroscopy. Besides, the dipole moments of selected open and cyclic associates were determined by DFT (density functional theory) calculations. All measurements we...

FTIR spectra of 1-hexanol trapped in a nitrogen matrix were registered in the temperature range from 10 to 40 K. The experiment has shown that only non‑hydrogen-bonded alcohol molecules were present in the sample at 10 K. Conformational analysis using high-level ROCBS-QB3 ab-initio calculations ...

Multi-walled carbon nanotubes (MWCNTs) were functionalized by hexylamine (HA) in a promising, cost-effective, rapid and microwave-assisted approach. In order to decrease defects and remove acid-treatment stage, functionalization of MWCNTs with HA was carried out in the presence of diazonium reac...

Relative permittivities at 1 MHz, εr, and refractive indices at the sodium D-line, nD, are reported at 0.1 MPa and at (293.15–303.15) K for the binary systems 1-alkanol + n-hexylamine (HxA). Also, their corresponding excess functions are calculated and correlated. Positive values of the excess...

The properties of foams and foam films stabilized by silica particles modified with hexylamine, depending on concentrations of hexyl-amine, are characterised.

Hexylamine (HA) functionalized reduced graphene oxide (RGO-HA) was prepared via the modification of graphene oxide (GO) with HA, followed by reduction with hydrazine hydrate. The structure of RGO-HA was confirmed using various characterization techniques. RGO-HA was easily dispersed in several o...

The stabilization of the foam films from hexylamine by the silica particles correlates with the rheological properties of the dispersion phase.

The conditions of stabilization of emulsions with silica particles modified by hexylamine and the thickness of free water-in-oil films have been determined.

It is shown experimentally that modification of silica particles by short-chain surfactant like hexylamine leads to inversion of selective wetting angle θ of the particles and to phase inversion in the emulsions stabilized by the hexylamine-modified silica particles. Empiric diagram of emulsion...

Stable foams have been generated in low concentration aqueous dispersions of hexylamine-modified Laponite particles. The particles are of primary size 30 nm, modified with hexylamine molecules to render them partially hydrophobic or moderate flocculants. Infrared adsorption spectra and zeta pote...
