This work presents an investigation on phase equilibria in partially miscible systems comprised of water, esters, and alkanols. Experimental liquid–liquid (LLE) were determined for ternaries water+H2u–1Cu–1CO2CvH2v+1+CwH2w+1(OH) (u = 3,4; v 2,3; w 1–4) at 298.15 K the four corresponding water+ester binaries, temperature interval T [283–328] K. The results reveal a complex behavior ternary LLE. ...

Interfacial tension is a very important thermophysical property from both fundamental and practical points of view because of its role in mass transfer phenomena in which the liquid-liquid interface is involved. In fact, it is well known that this property influences many industrial processes: formation or breaking of emulsions, liquid extraction, enhanced oil recovery using water and/or surfac...

Screening of absorbents is essential for improving the removal rate carbon disulfide (CS2) waste air by absorption. In this work, UNIFAC model in Aspen Plus was utilized to calculate excess Gibbs function and absorption potential binary system CS2 with various alcohols, ethers, esters, amines, aromatic hydrocarbons. The results were used quantitatively compare efficiency each solvent theoretica...

This work investigates the modeling of the surface tension and the interface of liquid mixtures. Nine binary liquid mixtures of (DMSO+alcohols), (2-Propanol+2,2,4-trimethylpentane), (Tetrahydrofuran+2-Propanol), (Tetrahydrofuran+2,2,4-trimethylpentane), and (ethano+glycerol) are considered. Additionally, one ternary liquid mixture of (Tetrahydrofuran+2-Propanol+2,2,4-trimethylpenta...

With the increased amount of focus is being put towards reducing the emissions results from fossil fuel usually composed of hydrocarbons and impurities. The study aim at utilizing the ability of 1-octyl-3-methylimidazolium tetrafluoroborate [OMIM][BF4]. Ionic liquid as the suitable solvent for the extraction of the thiophene and its derivatives from the model gasoline. The proces...
