August 1, 2001

Author(s)

D Behar, Carlos A. Gonzalez, Pedatsur Neta

Radiolysis of liquid 1-butyl-3-methylimidazolium (BMI +) salts leads to formation of several species with similar absorption spectra. To identify and characterize these species, experiments were carried out with BMI + in solution under various conditions

The Bancroft Point and Vapor-Liquid Equilibria in the System Benzene Plus Isopropanol

November 1, 2000

Author(s)

J. R. Elliott, James C. Rainwater

Vapor-liquid equilibria for the title system indicate azeotropic behavior with the composition of the azeotrope shifting from being benzene-rich at low pressure to isopropanol-rich at high pressure. We attribute this behavior to the nature of the Bancroft
