Modeliranje ravnoteže kapljevina-kapljevina u kvazi-sedmerokomponentnim sustavima s niskotemperaturnim eutektičkim otapalima kao ekstrakcijskim sredstvima

Liquid-liquid equilibria were experimentally investigated in systems in which the first component was aliphatic (n-hexane, n-heptane or i-octane) or aromatic hydrocarbon (toluene), the second component was pyridine or thiophene, and the third quasi-component was DES consisting of choline chloride and glycerol or choline chloride and ethylene glycol, at 25 °C and atmospheric pressure. The equilibria were successfully described by the NRTL and UNIQUAC models. The same models were successfully applied to describe the liquid-liquid equilibria in quasi-seven-component systems that comprised all the mentioned low molecular weight components and one DES. The restrictions of the models were discussed; it seems that the preference can be given to the UNIQUAC model.

Ravnoteže su uspješno opisane modelima NRTL i UNIQUAC. Isti su modeli uspješno primijenjeni i za opis ravnoteža kapljevina-kapljevina i u kvazi-sedmerokomponentnim sustavima koji uključuju sve navedene niskomolekulske komponente i jedan DES. Raspravljena su ograničenja modela; čini se da se prednost može dati modelu UNIQUAC. Ovo djelo je dano na korištenje pod licencom Creative Commons Imenovanje 4.0 međunarodna

Nomenclature note: Definitions of Terms Relating to Individual Macromolecules, Macromolecular Assemblies, Polymer Solutions, and Amorphous Bulk Polymers (Part II)

Ovaj dokument definira nazive povezane sa svojstvima pojedinačnih makromolekula, makromolekulskih nakupina, polimernih otopina i amorfnih polimernih tvari. U odjeljku o polimernim otopinama i amorfnim polimernim tvarima razmatraju se opće i termodinamičko nazivlje, razrijeđene otopine, fazno ponašanje, transportna svojstva, metode raspršenja svjetlosti i separacijske metode. Preporuke su revizija i proširenje nazivlja IUPAC-a objavljenog 1989., koje se ticalo pojedinačnih makromolekula, makromolekulskih nakupina i razrijeđenih polimernih otopina. Uvedeni su novi nazivi koji pokrivaju glavna teorijska i eksperimentalna saznanja do kojih se u međuvremenu došlo. Polielektroliti nisu uključeni. Ovo djelo je dano na korištenje pod licencom Creative Commons Imenovanje 4.0 međunarodna.This document defines terms relating to the properties of individual macromolecules, macromolecular assemblies, polymer solutions, and amorphous bulk polymers. In the section on polymer solutions and amorphous bulk polymers, general and thermodynamic terms, dilute solutions, phase behaviour, transport properties, scattering methods, and separation methods are considered. The recommendations are a revision and expansion of the IUPAC terminology published in 1989 dealing with individual macromolecules, macromolecular assemblies, and dilute polymer solutions. New terms covering the principal theoretical and experimental developments that have occurred over the intervening years have been introduced. Polyelectrolytes are not included.
