Hydrogen reduction of tubular nickel and nickel magnesium chrysotiles in a microbalance produced high Ni surface areas (10–30 m2/g) and uniform size distributions centered about 3 nm at 250 °C and increasing to a mean of 8 nm at 550 °C. The areas

Olefin treatment of molybdena-alumina at 200 °C results in the deposition of a residue which is tenaciously held to the surface and gives a very selective catalyst for olefin disproportionation. Molybdena promotes the deposition of residue since onl

The effect of adding various promoter metals to cobalt-molybdenum-alumina on the cyclohexane-thiophene (donor-acceptor) reaction was investigated. It was found that most of the transfer of hydrogen from cyclohexane to thiophene is indirect i.e., cycl

The production of hydrogen via the catalyst-assisted decomposition of water was investigated under mild conditions for the reaction Zn + H/sub 2/O ..-->.. ZnO + H/sub 2/. Hydrogen yields were determined for reaction temperatures of 303, 333, and 353

A novel three-component catalyst system has been found which is very active for the polymerization of isoprene. The catalyst consists of iron(III)acetyl-acetonate-triethylaluminum and specific bidentate ligands. The three bidentate ligands found whic

Bismuth oxide, Bi2O3, serves as an oxidant for the conversion of propylene to mainly 1,5-hexadiene. The main secondary product is benzene with small amounts of normal and cyclohexadiene also formed. The formation of 1,5-hexadiene most likely involves

Addition of thallium to alumina results in a reduction of surface acidity (as measured by ammonia adsorption) and the inhibition of double-bond isomerization. Adding thallium to molybdenum-alumina results in the promotion of high selectivity for olef

Silica gel, activated alumina, platinized asbestos, and partially reduced zinc oxide were found to have no effect on the rate of racemization of several complexes studied. Raney nickel caused the decomposition of [Co(en)3]Cl3. Activated carbon decomp

The racemization of the [Co(en)3]3+ ion in the presence of activated carbon was found to be retarded by H2SO4, to a slightly lesser extent by Li2SO4 or MgSO4, and to a slight extent by Na2SO4. Salts containing the ClO4−, NO3− or NO2− ions accel
