چکیده

In a previous work, simultaneous heat and mass transfer between a freely moving object and a gas fluidized bed of adsorbent particles were investigated. Sublimation of naphthalene spheres into a 13X molecular sieve bed was used as amodel system.P In an attempt to give an interpretation of these experimental data, the isotherms and the adsorption heat of this adsorbent/adsorbate pair have been determined and are report ed in the present paper. Two well-known gas-solid chromatography techniques, thoroughly described elsewhere.' " were used in a slightly modified from: the so-called "continuous injection" and "pulse injection" methods. With the first, a high concentration of adsorbate could be reached between 40 °C and 200 "C, The second method, used at higher temperatures (up to 400 °C), gave access to the region of isotherms corresponding to low adsorbed quantity.

Large-scale Solution Synthesis of Phosphorothioate Oligonucleotides: A Comparison of the Phosphoro- amidite and Phosphotriester Dimeric Approaches

Synthesis of oligonucleotides is turning into a large scale production, since they are increasingly demanded as new powerful drugs, as well as probes and primers in diagnostic kits. Synthesis of large quantities of these nucleic acid derivatives is a prerequisite for their successful commercialization, especially as antisense drugs, which represent their widest field of application. A simple an...

Electrokinetic Behaviour and Interaction with Oxalic Acid of Different Hydrous Chromium(III) Oxides

Three samples of hydrous chromium(III) oxide have been prepared by different procedures, and their electrokinetic mobilities have been measured. In mineral media, isoelectric points were found to be 8.45 0.15. This value is shifted from the solution isoelectric point by –0.35 0.15, due to the contribution of solvation energy to the energy of ionic adsorption. On the basis of a simple model, it ...

Formation Kinetics of an Emulsion in the System Water, Didodecyldimethylammonium Bromide, and Sodium Xylenesulfonate

The ternary phase diagram, the colloidal structures involved and the kinetics of an unusual emulsion formation in the system water, sodium xylenesulfonate (a hydrotrope) and didodecyldimethylammonium bromide (a surfactant) were determined using visual observation, optical microscopy, light scattering, electrical conductance and the stop-flow method. The results showed as expected that addition ...
