Experimental VLE data for binary systems of ethanol or water with three 1-ethyl-3-methylimidazolium ionic liquids (ILs) containing different anions were measured at normal pressure using the Siwoloboff procedure. ILs selected in this study those that appear to be suitable ethanol−water mixture separation by extractive distillation. Measured vapor–liquid equilibria described extended Raoult's la...

In a number of applications for which novel processes based on ionic liquids have been proposed, the recovery liquid from its mixture with molecular solvent is step critical importance viability process. this work, feasibility and conditions such by simple flash vapourisation explored particular case three dialkylimidazolium-based (namely 1-ethyl-3-methylimidazolium thiocyanate ([C2mim][SCN]), ...

Abstract Two widely used active pharmaceutical ingredients (API), ambroxol hydrochloride (AMB·HCl) and bromhexine (BMH·HCl), belong to the expectorant mucokinetic group of drugs. Their applications are found in treatment upper respiratory tract bronchopulmonary diseases. The compounds have similar chemical structures, but different enough distinguish their physicochemical properties. To underst...

This paper presents the ability of a new group contribution equation of state in the prediction of thermodynamic properties of alcohols, ketones and ethers. This equation of state, called MCORGC, is based on the Chain-Of-Rotators Group Contribution equation considering a NRTL type local composition mixing rule. The group parameters required to predict the thermodynamic properties of the oxygena...

The phase equilibriums of the ternary system KCl-(NH2)2CO-H2O at 303.15 K, 323.15 333.15 and 343.15 K were studied using isothermal dissolution equilibrium method, in which composition solid was determined by Schreinemaker’s wet residue method X-ray diffraction (XRD) method. It found that is a simple cosaturated system, without formation neither double salt nor solution. Wilson NRTL models empl...

In There are few simulation studies in the literature focusing on production of biodiesel from vegetable oil deodorization distillate (VODD), a waste originating processing stage, using hydrotalcite-hydroxyapatite as heterogeneous catalyst. this study, process was performed open interface software DWSIM® Version 6.3. The motivation relied positive performance catalyst during experimental studie...
