n-(diphenylphosphino)triethyl- and tributylammonium salts are introduced as easily prepared, cheap and stable ionic liquids that act as the condensing agent and media for the efficient esterification of acids with alcohols and phenols. this class of ionic liquids is immiscible with the ester products and thus allows simple and easy separation of the desired products from the reaction mixture.

This paper presents an interface tracking method for modelling the flow of immiscible metallic liquids in mixing processes. The methodology can provide an insight into mixing processes for studying the fundamental morphology development mechanisms for immiscible interfaces. The VOF method employed here utilises the piecewise linear for interface construction scheme as well as the continuum surf...

The generation of nanoalloys of immiscible metals is still a challenge using conventional methods. However, because these materials are currently attracting much attention, alternative methods are needed. In this article, we demonstrate a simple but powerful strategy for the generation of a new metastable alloy of immiscible metals. Au(1-x)Ni(x) 3D structures with 56 at% of nickel in gold were ...

Abstract A novel method for measuring the interfacial liquid film thickness between immiscible liquids of a slug/droplet in a micropipe is proposed. This method is capable of measuring an oil slug/droplet in water with the relative refractive index (m) between the immiscible liquids very close to one in a capillary tube. Unlike the measurement configuration for an air slug in water, an optical ...

We propose a volume fraction based approach to effectively simulate the miscible and immiscible flows simultaneously. In this method, a volume fraction is introduced for each fluid component and the mutual interactions between different fluids are simulated by tracking the evolution of the volume fractions. Different techniques are employed to handle the miscible and immiscible interactions and...

Large macromolecules with hydrophobic backbones are known to assemble at the interface between immiscible liquids. This assembly is often unpredictable because of the subtle interplay among hydrophobic interactions, hydrophilic solvation, structural constraints, and the thermodynamics of adsorption. In these studies, we employ vibrational sum frequency spectroscopy and interfacial tension measu...

Two Bacillus strains capable of emulsifying immiscible organophosphorus pesticides were isolated by enrichment methods. The emulsifying factor produced by Bacillus strain FE-2 has a high molecular weight, is Iysozyme sensitive and thermostable, and can be precipitated with trichloroacetic acid or ammonium sulfate; it may be a glycolipopeptide. It is specific for immiscible organophosphorus pest...

The establishment of methodologies for the mixing of immiscible substances is highly desirable to facilitate the development of fundamental science and materials technology. Herein we describe a new protocol for the compatibilization of immiscible polymers at the molecular level using porous coordination polymers (PCPs) as removable templates. In this process, the typical immiscible polymer pai...

CO2 flooding, a promising technique of enhanced oil recovery, is widely used for its capability boosting and reducing greenhouse gas emissions. In this study, the displacement performance supercritical tested in laboratory under immiscible flooding. The results show that: Supercritical improves by virtue low viscosity, high diffusivity, easy dissolution. With same pore volume (PV), flooding sig...
