9 non-oxidative

For example,copper has relatively good corrosion resistance under non-oxidizing conditions. It can be alloyed with zinc to yield a stronger material (brass), but with lowered corrosion resistance. Flowever, by alloying copper with a passivating metal such as nickel, both mechanical and corrosion properties are improved. Another important alloy is steel, which is an alloy between iron (>50%) and other alloying elements such as carbon. [Pg.923]

Using a catalyst system of PdCl2, CuCH, HCl, and O2, the internal alkyne 20 is carbonylated at room temperature and 1 atm to give unsaturated esters[19]. This apparently oxidizing system leads to non-oxidative cu-hydroesterilica-tion. With terminal alkynes, however, oxidative carbonylation is observed. [Pg.474]

Other non-oxidative procedures have also been used to deaminate aziridines. For example, aziridines react with carbenes to yield ylides which subsequently decompose to the alkene. Dichlorocarbene and ethoxycarbonylcarbene have served as the divalent carbon source. The former gives dichioroisocyanides, e.g. (281), as by-products (72TL3827) and the latter yields imines (72TL4659). This procedure has also been applied to aziridines unsubstituted on the nitrogen atom although the decomposition step, in this case, is not totally stereospecific (72TL3827). [Pg.75]

Group IIB ineludes Zn, Cd and Hg. Zine has some resemblanee to magnesium but the other metals in the group have little in eommon. At room temperature mereury is unaffeeted by air, water or non-oxidizing agents whereas zine is more reaetive, albeit tempered by a proteetive hydroxide film, a property utilized in galvanizing. [Pg.29]

Many low-molecular-weight aldehydes and ketones are important industrial chemicals. Formaldehyde, a starting material for a number of plastics, is prepared by oxidation of methanol over a silver or non oxide/rnolybdenurn oxide catalyst at elevated temperature. [Pg.711]

Non-oxidative conversion of a tetrahydro-)8-carboline into a 3,4-dihydro derivative has also been described. Dehydration of 1-hydroxymethyl-1,2,3,4-tetrahydro-j8-carboline (146) yielded 1-methyl-3,4-dihydro-j8-carboline (135). Harmaline and l-methyl-3,4-dihydro-j8-carboline-3-carboxylic acid were obtained in an analogous manner. ... [Pg.116]

The reaction of ozone with an aromatic compound is considerably slower than the reaction with an alkene. Complete ozonolysis of one mole of benzene with workup under non-oxidative conditions will yield three moles of glyoxal. The selective ozonolysis of particular bonds in appropriate aromatic compounds is used in organic synthesis, for example in the synthesis of a substituted biphenyl 8 from phenanthrene 7 ... [Pg.219]

As previously stated, polyurethanes do not have the degree of chemical resistance enjoyed by the other elastomers. Specially designed chemical resistant polyurethanes are suitable for use in dilute non-oxidative acids and salts, but are not normally suitable for alkalis. They show good resistance to oils and solvents. Maximum temperature of use is usually about 80°C, but this temperature is very dependent on the chemical environment. [Pg.944]

Borides are relatively inert, especially to non-oxidizing reagents. They react violently with fluorine, often with incandescence. Reaction with other halogens is not as violent and may require some heat. Resistance to oxidation, acids, and alkalis is summarized in Table 17.5. In oxidation conditions, a layer of boric oxide is formed on the surface which passivates it to some degree. Boric oxide melts at 450°C and vaporizes at 1860°C. It offers good protection up to 1500°C in a static environments but it has low viscosity at these temperatures and tends to flow under stress and the protection it offers is limited.f k l... [Pg.439]
