The paper presents the results of microwave synthesis a Zn-B-P-oxide catalyst, which actively absorbs energy radiation, applied to surface an aluminum-reinforced Al/γ-Al2O3 carrier, in order further intensify process acylation diethylamine with m-toluic acid diethylamide (DETA) under conditions exposure field. ob-tained demonstrate possibility realizing thermal regime, is formed reaction zone d...
Recent kinetic extensions of the nucleation theorem suggest that the logarithm of the steady-state nucleation rate has strong multilinear dependence on the log concentrations of condensable species present in the vapor phase. A further remarkable result is that the coefficients of this linear dependency provide a direct determination of the molecular content of the critical nucleus itself. Buil...
In this communication, we describe p-xylene oxidation with molecular oxygen at 373 K and atmospheric pressure using N-hydroximide catalysts. p-Xylene conversion was rather high over the first 2 h of reaction and complete by the end of the experiment. The product distribution curves versus reaction time are typical of consecutive reactions. The main intermediate product is p-toluic acid. Peak co...
A spectroscopic investigation of complexes used to catalyze the oxidative carbonylation of toluene to p-toluic acid was conducted. Rhodium complexes were analyzed by (103)Rh and (13)C NMR, UV-visible spectroscopy, and infrared spectroscopy. In the presence of vanadium and oxygen, the resting state of the Rh-catalyst was found to exist as a Rh(III) complex with carbonyl and trifluoroacetate liga...
In the title centrosymmetric dinuclear compound, [Cu(2)(C(8)H(7)O(2))(4)(C(8)H(8)O(2))(2)], four o-toluate anions form a cage around two Cu atoms in a syn-syn configuration. Two more o-toluic acid mol-ecules are apically bonded to the Cu atoms, which show a square-pyramidal coordination geometry. The acid H atoms are hydrogen bonded to the cage carboxyl O atoms [O⋯O = 2.660 (2) Å]. The mol-ecul...
o-Toluic acid, a photo-oxidation product in the atmosphere, and its monohydrate were characterized in the gas phase by pure rotational spectroscopy. High-resolution spectra were measured in the range of 5-14 Hz using a cavity-based molecular beam Fourier-transform microwave spectrometer. Possible conformers were identified computationally, at the MP2/6-311++G(2df,2pd) level of theory. For both ...
Toluic acid isomers are widely used as a chemical intermediate in manufacturing of dyes, pharmaceuticals, polymer stabilizers, insect repellent and other organic synthesis. The aim of present study was to evaluate the impact of biofield treatment on physical, thermal and spectroscopic properties of ortho isomer of toluic acid (OTA). The OTA sample was divided into two groups, served as control ...
The title compound, C(11)H(17)ClNO(+)·C(8)H(7)O(2) (-), was obtained by the reaction of chlorprenaline {or 1-(2-chloro-phen-yl)-2-[(1-methyl-eth-yl)amino]-ethanol} and p-toluic acid. The chlorpren-aline is twisted moderately with a C-C-C-C torsion angle of 109.6 (2)°. The two mol-ecules are linked by classical O-H⋯O and N-H⋯O hydrogen bonds. Further N-H⋯O hydrogen bonds link two of these units ...
