The most common method used for purifying biodiesel is washing with water. During the biodiesel washing process, two phases are formed, a water-rich phase and an ester-rich one. For this reason, ...

The preferred source of formaldehyde is paraformaldehyde (Malz Jr. et al. 1977). AOH was synthesized according to reaction (6). The solvents used (methanol, ethanol, n-propanol and n-buthanol) were of ...

Scientists from the Technical University of Munich and Lund University explored the use of new models for liquid-liquid chromatography based off pre-existing procedures for liquid-liquid extraction.

[2] Liquid‐liquid equilibrium for the ternary system of isopropyl acetate + 2‐propanol + glycerol at different temperatures under atmospheric pressure. Fluid Phase Equilibria (2016).

The EPA announced this week that 15 billion gallons of ethanol and biofuels will be blended in 2026 and 2027 with gasoline. Blends have a significant price advantage over unblended gasoline and are ...

As few as five electrons in a semiconductor can exhibit collective behaviour, forming a “Coulomb liquid”, according to researchers in Europe. This extends the study of correlated systems to electron ...

Using a Drude-based polarizable model, we investigate the liquid–vapor interface of hydrogen fluoride (HF) via molecular dynamics simulations. The interface displays a complex morphology with ...

An add-drop filter based on linear waveguides coupled through a ring resonator in a two-dimensional phononic crystal is introduced and its operation in detecting methanol concentration in ethanol is ...

Mixtures of cyclohexyl acetate and cyclohexanol were used as a mixed solvent to study liquid-liquid equilibria (LLE) of the acetic acid-water-cyclohexanol-cyclohexyl acetate quaternary system. The ...
