BACKGROUND Phenol is used as a raw material in the polycarbonate industry and incentive for bio-based plastics products increasing, so interest demand phenols. In renewable phenol production processes based on biomass, impurities derived from including other oxygenate compounds, are expected containing solution. Vapor–liquid equilibrium (VLE) of 2-Octanone was studied impact thereon to gain ins...

The separation of benzene and cyclohexane azeotrope is one the most challenging processes in petrochemical industry. In this paper, deep eutectic solvents (DES) were used as for cyclohexane. DES1 (1:2 mix tetrabutylammonium bromide (TBAB) levulinic acid (LA)), DES2 TBAB ethylene glycol (EG)) DES3 ChCl (choline chloride) LA) entrainers, vapor-liquid equilibrium (VLE) measurements at atmospheric ...

A simple fluid, described by pointlike particles interacting via the Lennard-Jones potential, is considered under confinement in a slit geometry between two walls at distance L_{z} apart for densities inside the vapor-liquid coexistence curve. Equilibrium then requires the coexistence of a liquid "bridge" between the two walls, and vapor in the remaining pore volume. We study this equilibrium f...

We report Monte Carlo simulations that show a closed-loop liquid-vapor equilibrium in a pure substance. This finding has been achieved on a two-dimensional lattice model for patchy particles that can form network fluids. We have considered related models with a slightly different patch distribution in order to understand the features of the distribution of patches on the surface of the particle...

Kusaka correctly points out that his Eqs. ~1! @Eq. ~39! in Ref. 1# and ~2! @Eq. ~43! in Ref. 2# are equivalent. Hence, the statement in Ref. 2 that Nishioka and Kusaka ‘‘arrived at a different expression for the work of embryo formation’’ is incorrect. Our misunderstanding stemmed from a failure to properly translate the notation of Ref. 1 into our own language. At the outset, however, we point...

The single-phase instability of high-pressure, steady, laminar counterflow diffusion flame is studied using the Vapor–Liquid Equilibrium (VLE) theory. a posteriori study focuses on identification potentially unstable regions emerging throughout full combustion states represented by high-pressure solution; specific emphasis placed middle branch solutions which are characteristic intermediary sta...
