Oxidation, partial

Although (SN)x does not react with water or acidic solutions, it slowly decomposes in alkaline solutions and it is readily oxidized. Partial bromination of (SN) or powdered S4N4 with bromine vapour yields the blue-black polymer (SNBro.4)x which has a room temperature conductivity of 2 x 10" cm . The sulfur-nitrogen chain in this... [Pg.280]

An important advance on these studies was the possibility of isolating AORs from Fe enriched media with obvious interest for an iron-sulfur center site labeling, with enhanced sensitivity of the Mossbauer studies. The work developed with bacterial systems is advantageous as compared with mammalian systems for isotopic labeling and opens the possibility of a direct measurement of substrate binding. Spectra of the enzyme in oxidized, partially reduced, benzaldehyde-reacted, and fully reduced states were recorded at different temperatures and with variable externally applied magnetic fields (222). In the oxidized enzyme, the clusters are diamag-... [Pg.401]

The proper location of data is also important in parameter-estimation situations. For the nitric oxide reduction reaction (K11), for example, the relative sizes of the three-dimensional confidence regions calculated after each observation are shown in Fig. 27. The size of the confidence region after 12 points taken according to a one factor at a time variation of hydrogen and nitric oxide partial pressures is seen to be equivalent the size of the region... [Pg.168]

Potential reactions of hydrocarbons are total oxidation, partial oxidation and steam reforming. These are shown below, using propene as an example, but similar equations would apply for other hydrocarbons. [Pg.62]

Figures 2 and 3 show the uptake of molybdenum oxide vapor by various sized particles of clay loam and calcium ferrite at 1400°C. Over the temperature and oxide partial pressure ranges used in these experiments, molybdenum oxide vapor consists of a mixture of M0O3, Mo2Oe, and Mo309 molecules whose proportions are temperature and pressure dependent. Data which can be used to calculate these ratios are available from a report of a mass-spectrometric study of the sublimation of M0O2 by Bums et al. (6). Usually, for convenience, the total vapor concentration (/xgram/liter) of all the polymers of M0O3 vapor were used in this report in place of partial pressures. In some situations it was necessary to compute the partial pressure of each polymeric species.

The sugar chain of ARS2 was oxidized, partially cleaved with 30 mM NaIC>4 at 4°C in the dark, and reduced with NaBH4 at room temperature overnight. For controlled Smith degradation, the polyol derivatives of ARS2 were hydrolyzed with 100 mM H2SO4 at room temperature for 16 hr. [Pg.436]

Oxidation of Coal and Coal Macerals. Extraction residues were oxidized as outlined in the experimental section. Two oxidation procedures were adopted - i). excess oxidant oxidation and ii). oxidant starved oxidation (partial oxidation). [Pg.305]

The oxidation of alcohols using azodicarboxylates has been previously reported (Yoneda, F. Suzuki, K. Nitta, Y. J. Org. Chem 1967,32,727—729). Control experiments were therefore performed to establish the need for copper salts in our oxidation procedure. Thus under our reaction conditions no aldehyde or ketone could be detected in the absence of the CuCl Phen catalyst even if phenanthroline was added as an activating base. Moreover, certain reactive alcohols were oxidized partially by CuCl Phen in the absence of the azo-derivative 19, though only in moderate yields. These control experiments thus clearly establish the key-role of the copper ion in these oxidations. [Pg.238]

The reaction kinetics were studied at temperatures between 240°C and 400°C, propylene oxide partial pressures between. 4 10 bar and 4.0 10 J bar and oxygen partial pressures between. 02 bar and. 2 bar. At steady state external diffusional limitations as well as diffusional effects inside the porous silver film were negligible (4). The kinetics and potentiometric results can be summarized as follows (4) ... [Pg.166]

TEMPO-catalysed oxidation of alcohols to carbonyl compounds with buffered aqueous NaOCl has found broad application, even in large-scale operations. Indeed, this selective methodology involves the use of safe, inexpensive inorganic reagents under mild reaction conditions. A new supported catalyst PEG-TEMPO 11, soluble in organic solvents such as CH2CI2 and AcOH, but insoluble in ethers and hexanes, was prepared and proved to be an effective catalyst for the selective oxidation of 1-octanol with various stoichiometric oxidants. When 11 was used at 1 mol% as a catalyst in combination with KBr (10 mol%) a slight excess of buffered bleach (pH = 8.6) as the terminal oxidant, partial over-oxidation of 1-octanol to octanoic acid was observed (91% yield in... [Pg.306]

A second solid substance, brownish yellow m colour, is described (Thomas, Cornet, rend., 1895, 121, 128) as resulting on heating ferric chloride in a current of nitric oxide. Partial reduction takes place, leaving a residue of composition corresponding to the formula, 2Feda.NO. A red hygroscopic and unstable compound, 10Fedj.NO, is also described. [Pg.93]

The colloids adsorb heavy metal ions and waterborne pollutants hence the fates of reactive elements and of many pollutants in the environment depend to a large extent on the movement of colloids in aqueous systems. The colloids in natural waters are characterized by an extreme complexity and diversity organisms, biological debris, organic macromolecules, various minerals, clays, and oxides, partially coated with organic matter. [Pg.820]

Niobium oxide (niobia) is an active catalyst, and can be used as a support for metal nanoparticles or oxides, and it can serve as a promoter in some reactions ([43 5] and references therein). Catalytic applications of niobia include the Fischer-Tropsch synthesis, oxidative dehydrogenation of alkanes, and oxidative coupling of methane. Studies on high-surface-area niobium oxides are complicated by a high degree of complexity because several stable structures (NbO, NbO and Nb O ) exist and the resulting surfaces of high-surface-area niobium oxides are not simple truncations of bulk niobia structures. This is even more so for supported metal oxides when two-dimensional thin films of niobium oxide partially cover a support oxide (Al Oj, SiOj, ZrOj, TiOj, [43]). Nb Oj was also used as a support for V, Cr, Re, Mo, and W oxide overlayers [45, 46]. [Pg.380]
