High pressure densities and derived thermodynamic properties for the (n-heptane plus n-octane plus ethanol) ternary system
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
The density of the ternary system (n-heptane + n-octane + ethanol) at temperatures from (293.15 to 373.15) K and at pressures from (0.1 to 40) MPa was experimentally determined at twelve compositions and the results are ...
Experimental Investigation and Modeling of Thermophysical Properties of Pure Methyl and Ethyl Esters at High Pressures
(Amer Chemical Soc, Washington, 2017)
Densities, speeds of sound, and refractive indices of methyl laurate, ethyl laurate, ethyl myristate, and ethyl oleate in the temperature range 288.15-343.15 K and viscosities from 288.15 to 373.15 K were measured at ...
Impregnation of cotton fabric with pyrethrum extract in supercritical carbon dioxide
(Elsevier Science Bv, Amsterdam, 2017)
This study discusses a possibility of cotton fabric impregnation with pyrethrum extract as a tick repellent in supercritical carbon dioxide. A solubility of pyrethrum extract in supercritical carbon dioxide has been ...
Isopiestic determination of the osmotic and activity coefficients of the {yMg(NO3)(2) + (1-y)MgSO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
Isopiestic (vapor pressure) measurements were made for aqueous mixtures of Mg(NO3)(2) and MgSO4 at T = (298.15 +/- 0.01) K with Mg(NO3)(2) ionic strength fractions y = (0.19691, 0.42542, 0.60113, 0.79583, and 1), along ...
Separation of phytochemicals from Helichrysum italicum: An analysis of different isolation techniques and biological activity of prepared extracts
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Helichrysum italicum presents a valuable source of natural bioactive compounds. In this work, a literature review of terpenes, phenolic compounds, and other less common phytochemicals from H. italicum with regard to ...
Volumetric, viscometric, spectral studies and viscosity modelling of binary mixtures of esters and alcohols (diethyl succinate, or ethyl octanoate plus isobutanol, or isopentanol) at varying temperatures
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
Density, viscosity and refractive index of four binary mixtures consisting of diethyl succinate or ethyl octanoate + 2-methyl-1-propanol or 3-methyl-1-butanol have been measured at atmospheric pressure and over the temperature ...
Excess molar volumes and viscosity behaviour of binary mixtures of aniline/or N,N-dimethylaniline with imidazolium ionic liquids having triflate or bistriflamide anion
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
In this study, densities and viscosities of four binary systems {aniline/N,N-dimethylaniline + 1-butyl-3-methylimidazolium triflate ([bmim][OTf])} and {aniline/N,N-dimethylaniline + 1-butyl-3-methylimidazolium bis(triflu ...
Multiscale and Multiphase Model of Fixed Bed Reactors for Fischer-Tropsch Synthesis: Intensification Possibilities Study
(Amer Chemical Soc, Washington, 2017)
A multiphase fixed-bed reactor (FBR) model for Fischer Tropsch Synthesis has been developed. A high level of details is considered for description of the phenomena on the reactor and particle scale. Detailed kinetics is ...
Determination of sterols and steroid hormones in surface water and wastewater using liquid chromatography-atmospheric pressure chemical ionization-mass spectrometry
(Elsevier Science Bv, Amsterdam, 2017)
The development and optimization of an analytical method for simultaneous extraction, determination and reliable confirmation of twenty steroids from different classes (human/animal and plant sterols, and natural and ...
Effects of Catalyst Activity, Particle Size and Shape, and Process Conditions on Catalyst Effectiveness and Methane Selectivity for Fischer-Tropsch Reaction: A Modeling Study
(Amer Chemical Soc, Washington, 2017)
We investigate effects of catalyst activity, catalyst particle shape (sphere, slab, and hollow cylinder), size (i.e., diffusion length), catalyst distribution (uniform vs eggshell type distribution for a spherical particle), ...
