Reducing agents hydrogen

In relation to the reducing agent, hydrogen gas, metal hydrides, and irradiation methods are the most investigated approaches used to produce metal NPs in ILs. [Pg.6]

Reducing Agents Hydrogen, lithium aluminum hydride, sodium borohy-dride, di-isobutyl aluminum hydride, iron metal Acids Sulfuric acid, hydrochloric acid, phosphoric acid, methanesulfonic acid, acetic acid, formic acid... [Pg.335]

Reducing agent Hydrogen is electropositive when it provides electrons to other substances in chemical reactions and, thus, is a reducing agent. Reduction is the opposite of oxidation. [Pg.44]

In this paper we report the application of bimetallic catalysts which were prepared by consecutive reduction of a submonolayer of bismuth promoter onto the surface of platinum. The technique of modifying metal surfaces at controlled electrode potential with a monolayer or sub-monolayer of foreign metal ("underpotential" deposition) is widely used in electrocatalysis (77,72). Here we apply the theory of underpotential metal deposition without the use of a potentiostat. The catalyst potential during promotion was controlled by proper selection of the reducing agent (hydrogen), pH and metal ion concentration. [Pg.309]

Catalytic reduction of steroid epoxides received considerable attention before the development of complex metal hydride reducing agents. Hydrogenation of 3 ,4a-epoxy steroids over platinum in acetic acid (Eq. 360), for example, gives rise to a mixture of 3 -hydroxy and 3 -acetoxy steroids.Reductive cleavage thus occur in the same direction as with lithium aluminium hydride in this particular instance —t.r. it gives an axis alcohol. [Pg.393]

Hydrides are powerful reducing agents. Hydrogen can form hydrogen bonds to lone pairs of electrons on highly electronegative elements. [Pg.806]

Black precipitate of bismuth metal Violet coloration with stannous salts the following interfere strong reducing agents (hydrogen sulfide, dithionites, sulfites, and selenites) also, U, V, Te, Hg, Bi, Au, Pd, Se, Sb... [Pg.537]

Other reducing agents (hydrogen or carbon, etc.) give the same results23. ... [Pg.67]

As a reducing agent, hydrogen peroxide releases 2 electrons and oxygen gas is formed ... [Pg.110]

The following interfere with the test strong reducing agents (hydrogen sulphide, dithionites, sulphites and selenites) V, U, Te, Hg, Bi, Au, Pd, Se, Te, Sb, Mo, W, Co and Ni. The reaction is not selective, but is fairly sensitive it can be used in the analysis of the Group IIB precipitate. Since iron(II) ions have no influence on the test, it may be applied to the tin solution which has been reduced with iron wire. [Pg.239]

Substitution of the reducing agent hydrogens by alkyl, -OR, or -CN groups... [Pg.103]

ALCOHOL ISOAMILICO PRIMARIO (Spanish) (123-51-3) Forms explosive mixture with air (flash point 109°F/43°C). Violent reaction with strong oxidizers, reducing agents, hydrogen trisulfide. Incompatible with acid anhydrides, acid chlorides, aliphatic amines, caustics, isocyanates, nitric acid, sulfuric acid. Attacks some plastics, rubber, and coatings. [Pg.57]
