Methanol, reaction

Reac tion (27-37) can occur in parallel with the methanol reactions, thereby overcoming the equilibrium limitation on methanol formation. Higher alcohols can also be formed, as illustrated by Reaction (27-25), which is apphcable to the formation of either linear or branched alcohols. [Pg.2377]

If the ethanolic or methanolic reaction mixture is made strongly acidic (pH < 3) before workup. the corresponding ethoxy- or methoxylactams are obtained. [Pg.808]

Iron porphyrins containing vinyl ligands have also been prepared by hydromet-allation of alkynes with Fe(TPP)CI and NaBH4 in toluene/methanol. Reactions with hex-2-yne and hex-3-yne are shown in Scheme 4. with the former giving two isomers. Insertion of an alkyne into an Fe(III) hydride intermediate, Fe(TPP)H, formed from Fe(TPP)Cl with NaBH4, has been proposed for these reactions. " In superficially similar chemistry, Fe(TPP)CI (present in 10 mol%) catalyzes the reduction of alkenes and alkynes with 200 mol% NaBH4 in anaerobic benzene/ethanol. For example, styrene is reduced to 2,3-diphenylbutane and ethylbenzene. Addition of a radical trap decreases the yield of the coupled product, 2,3-diphenylbutane. Both Fe(lll) and Fe(II) alkyls, Fe(TPP)CH(Me)Ph and [Fe(TPP)CH(Me)Ph] , were propo.sed as intermediates, but were not observed directly. ... [Pg.247]

C-methanol co-reaction with non-radioactive methyl iodide on Fe-Beta-300 The 11 C-methanol with non-radioactive methyl iodide was investigated to study the modification of the methanol reaction mechanism in co-reaction with methyl iodide. [Pg.343]

Anodic hydroxylation/methoxylation of furans has an exact chemical counterpart in the well-known bromine/methanol reaction, and the choice of method is not always easily made. One can compare the two methods particularly easily in syntheses of the flavoring component, the pyrone maltol 121, from the furan 122 since one group used the electrolytic method299 and another the chemical method.300... [Pg.230]

Reaction (F) represents one of the uses of methanol (reaction (C)), and is also an example in which reaction selectivity is an important issue. The reaction cannot be allowed to go to ultimate completion, since the complete oxidation of CH3OH would lead to C02 and HzO as products. Similarly, in reaction (D), benzene and other (unwanted) products are produced by dealkylation reactions. [Pg.513]

The resulting synthesis gas can subsequently be converted into methanol (Reaction 3) or polymerized to a mixture of hydrocarbons via the Fischer-Tropsch synthesis (Reaction 4) [37, 38]. These conversions usually require a H2/CO molar ratio close to 2 (Reactions 3 and 4), which contrasts with the H2/CO ratio of 0.5 that is delivered upon biomass gasification (Reaction 2). It can therefore be suitable to adjust the H2/CO ratio through the water-gas shift reaction (Reaction 5) ... [Pg.35]

First, rt is a total reaction rate of the methanol reactions. For both reactions, the first step of the reactions is likely the adsorb of methanol. [Pg.156]

The double arrows in the methanol reaction indicate that the reaction can go in either direction. There is a principle here that is taught in the sophomore P-chem class (Physical chemistry) of every chemical engineer. Methanol, in the vapor state, takes up only one-third the volume as the equivalent amounts of CO and H2. So in order to "push the reaction to the right," the process is run under pressure. That causes the compound that takes up less volume to be favored—synthesis gas to methanol rather than methanol to synthesis. [Pg.177]

The above reaction is utilized in large-scale industrial production of methanol. Reaction with boron trichloride over a hot tungsten or tantalum filament yields boron and hydrogen chloride ... [Pg.354]

The photosensitized oxidation of either trans-2-butene or a mixture of cis- and frans-2-butene in methanol using methylene blue as a sensitizer produced a single hydroperoxide—3-butene-2-hydroperoxide— cleanly at atmospheric pressure. The hydroperoxide was reduced to 3-butene-2-ol by treating the methanolic reaction solution with sodium... [Pg.108]
