Formylation of mesitylene, durene, and m-xylene derivatives containing electron-donor and electron-acceptor substituents by dichloromethyl methyl ether was studied in the presence of TiCl4. A series of functionally substituted sterically hindered benzaldehydes was prepared from the products of these reactions.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1609–1615, July, 1991. 相似文献

The thermodynamic aspects of adsorption equilibrium in systems with crystalline, liquid, and dense gas phases have been considered. The heats of phase transition and corresponding directions of mass transfer from the adsorbed phase into crystalline and liquid phases at different temperatures have been determined. The general equilibrium diagram in the coordinates Inp-T
–1 has been given with indication of the equilibrium lines of three-phase systems and characteristic points on the isosteres of adsorption,viz., the Gurvitsch and quasicritical points.Deceased.Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya, No. 8, pp. 1480–1485, August, 1995. 相似文献

Multiplicative inequalities of the type of Kh. Sh. Mukhtarov are also obtained. 相似文献

It is shown that (Ga,Mn)As layers formed by Mn+ ion implantation into GaAs and subsequent annealing by an excimer laser pulse with an energy density to 200–300 mJ/cm2 feature the properties of the p-type semiconductor and ferromagnetic properties. The threshold dose of implanted ions (~1015 cm–2) for activating Mn acceptors is determined. The sheet hole concentration and the Curie temperature increase with further increasing Mn+ ion dose. Hysteresis loops in the magnetic field dependences of the Hall effect, the negative magnetoresistance, and magnetic and structural studies suggest that the layers are analogues of single-phase ferromagnetic compounds (Ga,Mn)As formed by low-temperature molecular beam epitaxy. 相似文献

The results from magnetooptical studies of the influence of magnetochemical effects on the surface morphology and local magnetic
properties of FeN alloy thin films and thin-film systems that consist of alternating silicon dioxide and FeN layers of submicron
thickness, are shown. The dramatic influence of chemical etching on the surface morphology and magnetic characteristics of
the investigated samples is revealed. 相似文献

We consider, in a Hilbert space H, a problem on [0,1] for a second order elliptic operator-differential equation with operator-boundary conditions. We also consider second order elliptic differential equations with operatorboundary conditions in cylindrical domains in the case when operator-boundary conditions contain integral terms over the whole domain. In this case, the proof of the density of the domain of definition of operators in a space is difficult. When boundary conditions are local, this fact is a simple corollary of the density ofC
