thermodynamics of mixtures containing alkoxyethanols xxviii liquid liquid equilibria for 2 Phenoxyethanol selected alkanes
Thermochimica Acta, 2011Co-Authors: Víctor Alonso, Mario García, Juan Antonio González, Isaías García De La Fuente, José Carlos CobosAbstract:Abstract The coexistence curves of the liquid–liquid equilibria (LLE) for systems of 2–Phenoxyethanol (2PhEE) with heptane, octane, cyclohexane, methylcyclohexane or ethylcyclohexane have been determined by the method of the critical opalescence using a laser scattering technique. All the curves show an upper critical solution temperature (UCST), have a rather horizontal top and their symmetry depends on the relative size of the mixture compounds. UCST values are higher for systems with linear alkanes than for solutions including cyclic alkanes. For these mixtures, the UCST increases with the size of the alkyl group attached to the cyclic part of the molecule. It is shown that interactions between alkoxyethanol molecules are stronger when the hydroxyether contains an aromatic group. Data are used to determine the critical exponent for the order parameter mole fraction. Values obtained are consistent with those provided by the Ising model or by the renormalization group theory.

Efficacy of 2–Phenoxyethanol as an anaesthetic for two size classes of white sea bream, Diplodus sargus L., and sharp snout sea bream, Diplodus puntazzo C.
Aquaculture, 2006Co-Authors: H. Tsantilas, Apostolos D. Galatos, F Athanassopoulou, N. N. Prassinos, Katerina KousoulakiAbstract:The objective of this study was to evaluate the efficacy of 2–Phenoxyethanol as an anaesthetic for two size classes of white sea bream, Diplodus sargus L. (30 and 60 g), and sharp snout sea bream, Diplodus puntazzo C., (15 and 30 g) and establish the minimum concentration producing desirable anaesthetic effects on them. Fish were exposed to concentrations varying from 0.1 to 0.4 mL/L for a 60-min period. At concentrations of 0.1, 0.117 and 0.133 mL/L, 2–Phenoxyethanol failed to induce anaesthesia, whereas at concentrations of 0.167, 0.2, 0.3 and 0.4 mL/L all the fish were anaesthetised within 3 min of exposure. However, mortality was observed with the two higher concentrations. Induction time decreased and recovery time increased with increasing concentrations, being significantly concentration-dependent in both species (P ≤ 0.01). Following exposure of D. sargus to concentrations of 0.2 or 0.3 mL/L, both induction and recovery time were significantly weight-dependent (P ≤ 0.01). However, erratic weight dependencies of both induction and recovery time were observed in D. puntazzo. 2–Phenoxyethanol proved to be an effective and safe anaesthetic in both species permitting rapid and uneventful induction and recovery after a 60-min exposure period. The minimum concentration producing desirable anaesthetic effects was 0.167 mL/L. © 2005 Elsevier B.V. All rights reserved.
