Oxidation bismuth

In the vapor phase, acetone vapor is passed over a catalyst bed of magnesium aluminate (206), 2iac oxide—bismuth oxide (207), calcium oxide (208), lithium or 2iac-doped mixed magnesia—alumina (209), calcium on alumina (210), or basic mixed-metal oxide catalysts (211—214). Temperatures ranging...

A continuous process based on hydrodynamic cavitation can be employed to prepare a wide variety of metal oxides in grain sizes of 1 -10 nm, such as iron oxide, bismuth molybdate, perovskites, platinum-loaded zeolite, and other ceramics and superconductors [170]. The method uses a microfluidiser for mechanically generating hydrodynamic cavitation and the internal pressure of the liquid media is elevated from ambient pressure to between 1000 to 25 000 psi. 

When heated in air, bismuth burns with a blue flame, giving off clouds of its yellow oxide. Bismuths melting point is 271.40°C, its boiling point is 1,564°C, and its density is 9.807 g/cm. ... 

For this reaction, our aim was to improve the known catalytic action of iron oxides to an extent that the high activity of the generally used platinum catalyst would be equalled. Together with Ch. Beck, the author finally found iron oxide-bismuth oxide combinations, and iron oxide-manganese oxide-bismuth oxide combinations which were outstanding catalysts. An iron oxide-lead oxide catalyst proved to be less satisfactory (44). 

One of the simplest examples for such effects is the oxidation of ammonia with iron oxide-bismuth oxide as a catalyst. Here, the addition of bismuth oxide results in the formation of nitrous oxides as the main product whereas an iron oxide catalyst without bismuth oxide yields nitrogen almost exlcusively. Selectively guiding catalysts become increasingly important in the synthesis of organic compounds, e.g., in the hydrogenation of carbon monoxide where the type of obtainable product can be varied, within wide limits, by the kinds of catalysts and promoters which are employed.

Bismuth(lII) sulfide. Bi.Si. is precipitated by H2S from bismuth solutions. Complex sulfide ions form only slowly, so bismuth sulfide may be separated from the arsenic and antimony sulfides by this difference in properties. Lake the oxide, bismuth sulfide forms double compounds with tile sulfides of the oilier iuelids.

Further evidence supporting the bismuth center as a site of propylene activation comes from the analysis of the rates of formation and product distribution of propylene oxidation over bismuth oxide, bismuth molybdate, and molybdenum oxide. Bismuth molybdate is highly active and selective for the conversion of propylene to acrolein. However, the interaction of propylene with its component oxides yields very different results. Haber and Grzybowska (//. ), Swift et al. 114), and Solymosi and Bozso 115) showed that in the absence of oxygen, propylene is converted to 1,5-hexadiene over bismuth oxide with good selectivity and at a high rate, whereas molybdenum oxide is known to be a fairly selective but a nonactive catalyst for acrolein formation. The formation of 1,5-hexadiene over bismuth oxide can be explained if the adsorption of propylene on a bismuth site yields a ir-allylic species. Two of these allylic intermediates can then combine to give 1,5-hexadiene.

Bismuth combines slowly with oxygen at room temperamre. Bismuth oxide (Bi203) gives the metal its pinkish or yellowish tinge. At higher temperatures, the metal burns to form bismuth oxide. Bismuth also reacts with most acids.

Bismuth nitrate pentahydrate (Bi(N03)3-5H20) is found as lustrous hygroscopic crystals and smells like nitric acid. It is readily decomposed by water to subnitrate BiO(N03), but dissolves without decomposition in water containing nitric acid. It is soluble in organic solvents such as acetone, acetic acid and glycerol, but practically insoluble in ethanol and ethyl acetate. By heating above 590°C, it is converted to bismuth oxide. Bismuth subnitrate is a white, odorless and tasteless powder of non-stoichiometric composition its properties and composition vary considerably depending on...
