111. Rapid Expansion of Supercritical Solutions Technology.

Author

Walker, John M., Williams, John R., Clifford, Anthony A., Alessi, Paolo, Cortesi, Angelo, Kikic, Ireneo, and Carli, Fabio

Abstract

Particle size is a key factor for the performance in the use of different organic and inorganic materials. The first observation on the possibility of obtaining ultrafine powders through supercritical fluid (SF) processing was made in 1876 (1), but not until 1984 did Krukonis (2) demonstrate the potential of SFs for processing a variety of solids that are difficult to comminute. The great advantage of using SFs is in the possibility of producing solid phases with unique morphology at mild operating conditions. [ABSTRACT FROM AUTHOR]

126. On the application of solution of group theory to dilute mixtures of isomers

Abstract

One of the limitations of any group contribution method developed so far is the impossibility to distinguish among different isomers. This paper suggests a very simple procedure to extend the solution of group theory to mixtures containing isomers. The procedure suggested is based on theoretical considerations and is derived from phase equilibrium data for mixture of isomers in the dilute regions. A linear correlation is found between the surface area fraction (q) of the molecules and the ratio of the critical pressure over the critical temperature. Furthermore the investigation shows that the q values of the organic compounds which exhibit strong association phenomena should be substantially reduced: numerical values are reported depending upon the availability of experimental data.

127. A differential static apparatus for the investigation of the infinitely diluted region

Abstract

This work proposes a method for the determination of data at infinite dilution and at very low concentration based on the isothermal measurement of the difference in pressure between two static cells containing the pure component and the mixture respectively. The method is particularly suitable for investigating binary systems whose components differ strongly in volatility, and when other methods such as gas liquid chromathography or ebulliometry fail.

142. Polarity of phthalate esters in gas chromatography

Author

Alessi, Paolo, Kikic, Ireneo, and Papo, Adriano

Abstract

The importance of the concept of the “polarity” of stationary phases used in gas chromatography is discussed and a review of the principal methods proposed for the evaluation of gas chromatographic polarity is presented. These methods were employed for the gas chromatographic characterization of eight phthalate esters, and the discrepancies between the polarity scales obtained by different methods are considered.
