The catalytic influence of major metal species found with waste wood (Na, K, Ca, Mg, Zn, Pb, Cu) was studied during the gasification of nitrate salt impregnated charcoal with CO2 at 800degreesC in the kinetically controlled regime. In contrast with literat ...
Structured palladium catalysts suitable for three-phase reactions have been developed based on woven fabrics of active carbon fibers (ACF) as the catalytic supports. The Pd/ACF were tested in liq.-phase hydrogenation of 2-butyne-1,4-diol showing a selectiv ...
The title compd. was obtained by reaction of (tert-BuO)3SiSH with metallic Li. Crystals are monoclinic, space group P21/n, with a 13.088(3), b 27.188(5), c 17.525(4) .ANG., b 102.25(3) Deg; Z = 2, dc = 1.083; R = 0.036, Rw(F2) = 0.105 for 11,732 reflection ...
The gasification reaction of fir charcoal with CO2 was studied by isothermal thermogravimetric analysis under kinetic control. The derived reaction rate (r = dX/dt) as a function of the converted carbon mass (X) was compared with random pore model predicti ...
The reaction of itaconic anhydride with N2:CHCO2Et or Ph2C:N2 gave the expected spiro-derivs., which spontaneously rearranged; specifically, the adduct from Ph2C:N2 loses a dinitrogen mol., yielding a spirocyclopropane related to the known 5-azaspiro[2.4]h ...
The redn. of NO by CO or C3H6 in the presence of O2, a reaction of great technol. importance, was studied on porous polycryst. Rh catalyst films using a single-chamber and a wireless bipolar cell configuration. In the latter case the Rh catalyst films were ...
Below -60 and without catalyst, 1.2-dimethylidenecyclopentane (16), 1,2-dimethylidenecyclohexane (13), 1,2-dimethylidenecycloheptane (17), and 1,2-dimethylidenecyclooctane (18) add to sulfur dioxide in the hetero-Diels-Alder mode, giving the corresponding ...
Kinetics on the cheletropic addition of sulfur dioxide to (E)-1-methoxybutadiene (1) to give the corresponding sulfolene 2 (2-methoxy-2,5-dihydrothiophene-1,1-dioxide) gave the rate law d[2]/dt = k[1] SO2 with x = 2.6 +/- 0.2 at 198 K. Under these con ...
The reaction of 1-bromo-3-halo-2-iodobenzene (I; X = Cl) with butyllithium gives 62% (II; X = Cl) similarly reaction of [I; X = F(III)] gave 64% II (X = F). These reactions involve the immediate intermediacy of the halolithiobiphenyl (IV) and the penultima ...
This thesis deals with a laboratory study of heterogeneous reactions involving bromine and chlorine containing reservoir species on alkali salt substrates which are relevant to the marine boundary layer, and on ice substrates which are relevant to the lowe ...
