“…The results of our measurements are given in Fig. 3; also given for comparison in this figure are the data of Gurdial and Foster [5] obtained in a circulation setup and of Ke et al [7] obtained in a static setup. The errors of the results of indirect measurements were analyzed in accordance with the procedure described by Novitskii and Zograf [13].…”

The possibility of using the method of supercritical fluid extraction for purifying the product of synthesis of salicylic acid is revealed and confirmed experimentally. A continuous-flow experimental setup is used to investigate the solubility of salicylic acid and phenol in supercritical CO 2 and to purify the product of synthesis of salicylic acid at a temperature of 308 K in the pressure range from 7.8 to 12 MPa. The salicylic acid content of the resultant product conforms to the requirements of the State Pharmacopoeia.

“…So extensive a range of application of salicylic acid defines the high requirements of its purity. A convincing proof of this is provided, in particular, by the results of numerous investigations (for example, [3][4][5][6][7][8][9] of the supercritical state of materials, which were performed in numerous countries during the last decade.…”

In this work, we propose to correlate and predict the solubility in supercritical CO 2 of disubstituted aromatic isomers of hydroxybenzoic acid and methylbenzoic acid with a new methodology based on the expanded liquid theory, in which the solid-fluid equilibrium is modeled using the local composition model of UNIQUAC in which the interaction parameters are related to the solvent reduced density with an empiric exponential form equations. The experimental solubility of hydroxybenzoic acid isomers, methylbenzoic acid isomers and mixed isomers (mhydroxybenzoic acid+p-hydroxybenzoic acid) are used for evaluating the correlation and prediction capabilities of this new methodology. The results obtained using the proposed model show good agreement with the experimental data used.

“…Co-solvents are known to greatly enhance the solubility of solutes in CO2 [61][62] and perfluorohexane, which has a critical temperature of 175 °C and critical pressure of In VLS growth the mean nanowire diameter is determined by the dimensions of the saturated Au:Ge eutectic droplet from which they nucleate 13 . A large variation in the distribution of nanowire diameters in any given sample usually results from the agglomeration of the Au nanoparticles, or Au-Ge liquid alloy droplets, prior to nanowire growth.…”

Access to the full text of the published version may require a subscription. Differences in the ligand conformations on the surface of the Au nanoparticles and phase separation of the fluorocarbon/CO2 and hydrocarbon/toluene systems, gave rise to greater steric stabilisation of 2 the fluorous-capped Au nanoparticles in CO2, resulting in small diameter nanowires with a relatively narrow size distribution. Electrical analysis of the nanowires showed them to be p-type (hole) Rightssemiconductors.
