Synthesis of a polyhydroxyquinolizidine bearing a polyhydroxylated carbon side-chain
The lithium enolate of (-)-6-endo-chloro-5-exo-(phenyl-seleno)-7-oxabicyclo[2.2.1]heptan-2-one ((-)-4) added to (+)-(3aR, 4aR,7aR,7bS)-3a,4a,7a,7b-tetrahydro-6,6-dimethyl[1,3]dioxolo[4,5]furo[2, 3-d]isoxazole-3-carbaldehyde ((+)-5) giving a major aldol (+) ...
1999Carbon dioxide hydrogenation to methanol at low pressure and temperature
The measurements obtained were used to investigates the methanol synthesis reaction from pure carbon dioxide and hydrogen over binary (CuO/ZrO2) and ternary supported catalysts (CuO/ZnO/Al2O3). A comparison of different catalysts is presented. The influenc ...
EPFL1998Chemoselective Removal of Allylic Protecting Groups Using Water-Soluble Pd(OAc)2/TPPTS Catalyst
The removal of allylic protecting groups promoted by the catalytic system Pd(OAc)(2)/TPPTS has been achieved on bifunctional substrates with complete chemoselectivity and high efficiency, in aqueous media. By lowering the amount of palladium catalyst, subs ...
1997Sodium compounds as catalysts for methanol dehydrogenation to water-free formaldehyde
Catalysts based on alkali compds. were active in the dehydrogenation of MeOH in absence of O. Na2CO3 doped with In showed a selectivity of ?75% for MeOH conversion ?60%. [on SciFinder (R)] ...
1990Base Promoted 1,4-Elimination Reactions : On the Origin of an Eventual syn-Stereoselectivity
Rate ratios were obtained for the base-catalyzed 1,4-dehydrochlorination of (E)- and (Z)-Me3CCCl:C:C:CClCMe3 to give Me3CC.tplbond.CC.tplbond.CCMe3. In the KOMe/MeOH or KOCMe3/Me2SO systems the reactivity of both isomers was similar. With KOCMe3 in Me3COH, ...
1981Studies on the instability of isothermal heterogeneous fixed bed reactors
Oscillation of the reaction rate, leading to strong, irregular oscillation of the conversion in dependence on the time, and sudden conversion changes occurred in certain temp. and concn. regions in the exptl. study of the catalytic hydrogenation of C2H4 wi ...
1975Studies on instability of isothermal heterogeneous fixed-bed reactors
Oscillation of the reaction rate, leading to strong, irregular oscillation of the conversion in dependence on the time, and sudden conversion changes occurred in certain temp. and concn. regions in the exptl. study of the catalytic hydrogenation of C2H4 wi ...
1975Control of effective rate of heterogeneous catalytic reactions by forced variation of concentration
Addnl. data considered in abstracting and indexing are available from a source cited in the original document. The effect of varying the feed concn. as a periodic rectangular function was studied in the hydrogenation of C2H4 in a fixed bed of an Al2O3-Pt c ...
1974Effect of oscillation phenomena on material transport
A study was made of the effect of the frequency and intensity of the gas oscillations on mass transfer between a gas and a solid surface, under conditions of a linear oscillation direction and a precisely defined surface shape, for the purpose of obtaining ...
1970In Situ Control of the Adsorption Species in CO2 Hydrogenation: Determination of Intermediates and Byproducts
Andreas Züttel, Ligang Wang, Kun Zhao
CO2 hydrogenation over catalysts is a potentially exciting method to produce fuels while closing the CO2 cycle and mitigating global warming. The mechanism of this process has been controversial due to the difficulty in clearly identifying the species pres ...
