The ionic liquid (IL), tetrabutylphosphonium trifluoroacetate ([P4444][CF3COO]), showed a low critical solution temperature (LCST)-type phase transition in water. Using this temperature-sensitive IL and the Triton X-100/H2O system, the reversible transformation between micelles and microemulsions ...

Hydrogen evolution and corrosion rates for an Alloy 800H flow‐through reactor operating under supercritical water conditions were determined. Experiments were performed in the temperature range of 650 to 750 °C both with deoxygenated feed water, with an O2 concentration of less than 10 μg L−1 ...

Summary In this study, the copolymerization of vinyl acetate (VAc) and butyl acrylate (BuA) in water semicontinuous emulsions made with the nonionic surfactants, Triton Xs, was studied as a function number of ethylene oxide (EO, X) and their concentrations. The copolymerization of VAc and BuA ...

The spatial and orientational structure of the solvation shell of benzene in sub- and supercritical water are investigated by means of molecular dynamics simulations. The present study reveals different local organization of water molecules at different parts of the solute. The π-hydrogen-bonding ...

The solubility of 2,5-di-tert-butylhydroquinone (DTBHQ) in acetone, ethyl acetate, methanol, and the mixtures of ethanol and water was measured and correlated in the temperature range between 278.95 K and 346.15 K. It was found that the solubility in acetone increases more rapidly with increasing ...
