Multiparameter correlations for description of thermodynamic parameters of solvation: I. Enthalpy of nonspecific solvation

Applicability of a linear solvation-energy approach for descripition of the solvation enthalpies of nonelectrolytes is examined. In most cases a good fit of experimental solvation enthalpies can be attained. However, the resulting data are difficult to interpret in terms of different types of intermolecular interactions

EXTERNAL ECONOMIC POTENTIAL OF OIL-PROCESSING INDUSTRY OF RUSSIA

Steady bases of development of foreign economic relations of oil refinery in our country were so far created. At the same time, a number of restrictions of realization of the external economic capacity of branch still takes place. In the article major factors and tendencies of development of foreign trade in oil products in Russia at the present stage are generalize

Multiparameter correlations for describing thermodynamic parameters of solvation: II. Enthalpy of specific interaction

The applicability of the approach based on the linear solvation energy relationship to describing the enthalpies of specific solvent-solute interactions was examined. In associated solvents, this approach reflects the contribution of specific interaction incorrectly. Although the enthalpies of solvation as a whole are described well, this is an "occasional" result and is due to averaging over different compounds and redistribution of contributions from other types of interactions. A modification of this approach was suggested to take into account the effect of reorganization of an associated solvent

THE LATEST CHANGES IN PRODUCTION STRUCTURE OF WORLD OIL PROCESSING

Development of the modern world economy is impossible without broad use of production of oil-processing industry. In modern conditions there is a serious shift in geography of world oil processing. In article the newest tendencies of change of structure of world oil-processing industry in regional aspect are estimated

Photoinduced activation of arene C-H bonds with (η5-cyclopentadienyl)-trimethylplatinum(IV): A possible role of CpPtR2H

(η5-Cyclopentadienyl)trimethylplatinum(IV) reacts with ArMe arenes rather than alkanes or benzene under heating to 150 °C in the dark or under irradiation with light at room temperature by a radical mechanism to produce (η5-cyclopentadienyl)dimethyl(arylmethyl)platinum(IV) complexes, and the expected complex CpRR2(H) is unstable under the reaction conditions, as found by the reduction of CpRMe2I with complex metal hydrides
