A diblock copolymer template of nonbornene derivatives was employed to prepare Bi2O3 nanoparticles. The precursor formed within the nano-size micelles of diblock copolymer after introducing BiCl3 into the template. The precursor was calcined to produce Bi2O3 nano particles, XRD and TEM show that these nanoparticles are the α-Bi2O3 phase and have an average size from 10 to 30 nm. The photocatalytic performance of Bi2O3 particles has been tested in the degradation of methyl orange solution at visible light condition.

Liquid-liquid equilibrium tie-line data were examined at atmospheric pressure and at 298.15 K for ternary mixtures of (water + methanol + linalool) as well as (water + ethanol + linalool). The distribution ratios of alcohol between organic and aqueous phases are discussed. The immiscible area of (water + methanol + linalool) system is wider than that for the ethanol system. The experimental liquid–liquid equilibrium data were satisfactorily fitted by means of an extended UNIQUAC model.

Isobaric liquid-liquid equilibrium tie-line data were determined at atmospheric pressure and at 283.15 and 313.15 K for the mixture (water + methanol +citral). The miscibility for the ternary (water + methanol + citral) LLE was increasing as the temperature increased. The experimental liquid–liquid equilibrium data have been satisfactorily represented by using an extended UNIQUAC model.

Liquid-liquid equilibrium tie-line data were examined for ternary mixtures of (water + methanol + geraniol) and (water + ethanol + geraniol) at 298.15 K. The distribution ratios of alcohol between organic and aqueous phases are discussed. The immiscible area of (water + methanol + geraniol) system is wider than that for the ethanol system. The experimental liquid–liquid equilibrium data have been satisfactorily represented by using an extended UNIQUAC model.
