Unified Description

Theoretical relation derived in the last study for calculation of the mass transfer coefficient in the region of not fully developed concentration profile at high Schmidt numbers has been verified experimentally. This experimental study has been devoted to measurements of the rate of benzoic acid dissolution into aqueous solutions of glycerol from the internal surface of the pipe of circular cross section in the range 933 ⪬ Sc ⪬ 225 000 and 5 000 ⪬ Re ⪬ 50 000. It has been possible to explain on basis of the theoretical model, the differences between the data of various authors and to obtain a unified description of the phenomena.

Molal Volumes

The solubility of toluene and benzaldehyde was measured in NaBr and (n-Pr)4NBr aqueous solutions at 25 °C, and the solubility of benzoic acid and nitrobenzene was measured in the same systems at 10, 25, and 40 °C. The apparent molal volumes of the four nonelectrolytes were also determined from the densities of the saturated aqueous solutions.The volumes of mixing of the nonelectrolytes in water are all negative but become less so as their polarity increases. With the exception of benzoic acid, the salting-out by NaBr and the salting-in by (n-Pr)4NBr both decrease with increasing polarity of the nonelectrolytes. Both salting effects increase with temperature. These trends can be explained with existing theories of salting-out and salting-in.

High Adsorption Capacity

To achieve a fast adsorption rate and a high adsorption capacity in the selective adsorption of Cr(vi) from wastewater, a novel Cr(vi) ion imprinted polymer (Cr(vi)-IIP) was synthesized by bulk polymerization with 4-vinyl pyridine (4-VP) as a functional monomer.

Rapid Proton

Aromatics undergo rapid proton-deuterium or -tritium exchange in aqueous solutions containing Raney nickel alloy. The specificity of exchange in benzoic acid, anthranilic acid, pyridine and aniline is investigated by degradation and mass and N.M.R. spectrometry. Positions meta and para to carboxylate are most readily exchanged.
