New catalytic systems are still in development to meet the challenge of regulations concerning the emission of volatile organic compounds (VOCs). This is because such compounds have a significant impact on air quality and some of them are toxic to the environment and human beings. The catalytic ...
Ignition delay experiments for gas phase n-nonane/air mixtures have been performed behind reflected shock waves over a wide temperature range of 684–1448 K, pressures of 2.0–15.0 atm, and equivalence ratios of 0.5, 1.0, and 2.0. Ignition delay times were determined using electronically excited...
The applicability of the n-nonane pre-adsorption method for characterising the porosity in clays is presented. Na-SD, a Na+-exchanged purified bentonite, and materials obtained by Al3+-exchange and acid treatments of Na-SD and SAz-1 were used. Nitrogen adsorption isotherms, at −196 °C, were det...
In this paper, we present density and speed-of-sound experimental measurements for n-nonane at temperatures between (283.15 and 473.15) K and pressures up to 68 MPa and 390 MPa respectively. The density measurements were performed with a vibrating-tube densimeter and the speed-of-sound measureme...
The isothermal vapour-liquid and vapour-liquid-liquid equilibria of five binary refrigerant + n-alkane systems at near ambient temperatures were measured using a static-analytic apparatus and a static-synthetic apparatus. The phase equilibrium data for the systems of trifluoromethane (R-23) + n-...
Solubility of light fullerenes (C60 and C70) in n-nonane was investigated in the ranges of pressure form 0.1 MPa up to 100 MPa and temperature from 298.3 K to 353.3 K. Under isothermal conditions, the solubility, expressed as weight fraction of the fullerene in the solution, increases monotonous...
Cyclic voltammetry, controlled-potential electrolysis, and double-potential-step chronocoulometry have been used to characterize the catalytic reduction of 1-bromooctane by nickel(I) salen electrogenerated at a mercury cathode in dimethylformamide containing tetramethylammonium tetrafluoroborate...
A dinickel Schiff base complex (Ni2(II)L) containing two salen units has been synthesized and characterized by NMR and mass spectrometry. The complex was used for the catalytic reduction of 1- and 2-bromooctanes and its electrochemical behavior, which is similar to that of nickel salen, was stud...
Ni2P/SiO2 and bimetallic NiMP/SiO2 (M = Co, Fe, Mo, W; Ni/M atomic ratio=5) catalysts were prepared by the temperature-programmed reduction method. The catalysts and their precursors were characterized by means of UV–Vis DRS, H2-TPR, XRD, TEM, CO chemisorption and NH3-TPD. Their performance for...
A series of Ni2P/AlMCM-41-x bifunctional catalysts with different Si/Al ratios (x) were synthesized by in situ phosphorization of Ni/AlMCM-41-x with triphenylphosphine (nominal Ni/P ratio of 0.75) at 300 °C on a fixed-bed reactor. For comparison, NiP/AlMCM-41-5-TPR was also prepared by the TPR ...
SiO2 supported bifunctional MoP catalysts modified with different metal promoters (Ni, Ru, Pd, Pt), where Mo/Ni and Mo/M(M = Ru, Pd and Pt) atomic ratios was respectively 10 and 40, were prepared by TPR method from the phosphate precursors. It was found that the introduction of metal promoters f...
In this study, silica-supported Ni–Mo catalysts were prepared by co-loading Ni and Mo species on silica materials with different specific surface areas to investigate the effects of the supporting material's surface area on the physicochemical properties of the loaded metal species and the...
A series of sulfur-free Ni/γ-Al2O3 catalysts with different metal Ni loading amount were prepared by impregnation method. The prepared catalysts and corresponding precursors were investigated through XRD, BET, H2-TPD, and H2-TPR analysis methods. The effect of Ni loading on catalytic performanc...
The cross-metathesis of methyl oleate (MO) with cinnamaldehyde (CA) to yield 2-undecenal, methyl 11-oxo-9-undecenoate, methyl 10-phenyl-9-decenoate and 1-decenylbenzene was investigated using the second-generation Hoveyda-Grubbs Ru complex (HG2). Self-metathesis of methyl oleate was the main und...
The metathesis of esters of unsaturated carboxylic acids catalyzed by the WCl6/Me4Sn system is influenced by the presence of free acids. The extent of their effect depends on how they are delivered into the reaction mixture. If the acid is allowed to react with WCl6 (either free or as an ad-mixt...
Several non-metallocene-type titanium(IV) complexes containing phenoxy-phosphine or thiophenoxy-phosphine ligands of type, (2-R1-4-R2-6-PPh2-C6H2X)2TiCl2 (2a: X = O, R1 = R2 = t-Bu; 2b: X = O, R1 = R2 = cumyl; 2c: X = S, R1 = SiMe3, R2 = H) have been synthesized by treating TiCl4 with the corres...
We present results of photoluminescence quenching measurements of sensor elements based on as-prepared porous silicon, oxidized porous silicon and methyl-10-undecenoate functionalized porous silicon. Photoluminescence sensor response was quantitatively studied for a set of C1–C6 alcohols in gas...
In this paper, we present a process concept for the atom economic hydroesterification of renewable methyl 10-undecenoate in thermomorphic multicomponent solvent (TMS) systems. Resulting dimethyl dodecanedioate is a polymer building block used e.g. in Nylon 6,12. As a suitable recycling technique...
Butyl 10-undecenoate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog methyl undec-10-enoate (CAS # 111-81-9) show that butyl 10-...
The solubilities of ricinoleic acid, methyl ricinoleate, and methyl 10-undecenoate were determined in supercritical carbon dioxide (SCCO2). The solubility measurements were performed in the range of temperatures of 313–333 K, and pressures of 10–18 MPa. The solubilities followed a trend of met...
