Calculation and prediction of multicomponent azeotropes with activity coefficient modelsCálculo y predicción de azeótropos multicomponentes con modelos de coeficientes de actividad
(Centro de Informacion Tecnologica, 2008-05)
This paper studies the multicomponent azeotropic capacity prediction of activity coefficient models. Wilson and UNIFAC models are used for homogeneous azeotropes while UNIQUAC and UNIFAC models are used for heterogeneous ...
One-step synthesis of N, N′-substituted 4-imidazolidinones by an isocyanide-based pseudo-five-multicomponent reaction
(Royal Society of Chemistry, 2018-11-01)
A pseudo-five-multicomponent reaction involving an isocyanide, a primary amine, two molecules of formaldehyde and water is reported, which gives N,N′-substituted 4-imidazolidinones when trifluoroethanol is used as the ...
Steroid diversification by multicomponent reactions
(Beilstein-Institut, 2019-06)
Reports on structural diversification of steroids by means of multicomponent reactions (MCRs) have significantly increased over the last decade. This review covers the most relevant strategies dealing with the use of ...
Simultaneous improvement of ketoconazole solubility, antifungal and antibiofilm activity by multicomponent complexation
(Future Medicine Ltd., 2020-11)
A novel multicomponent complex (MC) of ketoconazole (KET) with β-cyclodextrin (β-CD) and N-acetylcysteine (NAC) was developed with the purpose of improving the solubility as well as the antifungal and antibiofilm activity ...
Multicomponent synthesis of acylated short peptoids with antifungal activity against plant pathogens
(Springer, 2012-02)
In this article, we describe the synthesis of a small library of short peptoids composed of four glycine residues and acylated with a fatty acid that showed a remarkable in vitro activity against two fungal plant pathogens. ...
Hydrotalcites in organic synthesis: Multicomponent reactions
(Bentham Science Publishers, 2018-07)
Background: The use of solid bases as heterogeneous catalysts allows the replacement of conventional bases in Organic Chemistry, being of outmost importance. Lamellar double hydroxides or hydrotalcites are materials having ...
Ternary hydrotalcites in the multicomponent synthesis of 4H-pyrans
(Multidisciplinary Digital Publishing Institute, 2020-01)
Lamellar double hydroxides (LDH) with double divalent cations were synthesized by the co-precipitation method and studied in the multicomponent synthesis of 4H-pyrans. The solids obtained were characterized by X-ray ...
Equilibrium mono- and multicomponent adsorption models: From homogeneous ideal to heterogeneous non-ideal binding
(Elsevier Science, 2020-06)
Aqueous sorption processes play an important role in, for example, pollutant binding to natural nanoparticles, colloid stability, separation and enrichment of components and remediation processes. In this article, which ...
Prediction of the Water Activity in Multicomponent Solutions by a Simple and Accurate Equation and Derivation of Zdanovskii’s Rule
(Springer/Plenum Publishers, 2019-03)
A simple equation is derived for the prediction of the water activity as a function of the molal concentrations of a multicomponent mixture, a1(m2 , m3 ,.., mn+1). It consists basically of a series expansion whose coefficients ...
Efficient multicomponent synthesis of diverse antibacterial embelin-privileged structure conjugates
(Molecular Diversity Preservation International, 2020-07)
A library of embelin derivatives has been synthesized through a multicomponent reaction from embelin (1), aldehydes and privileged structures such as 4-hydroxycoumarin, 4-hydroxy-2H-pyran-2-one and 2-naphthol, in the ...
