Abstract

Dibenzyl ether can be readily cleaved to form primarily benzaldehyde and toluene as products, along with minor amounts of bibenzyl and benzyl benzoate, in the presence of a catalyst system comprising a Group 6 metal, preferably molybdenum, a salt, and an organic halide. Although useful synthetically for the cleavage of benzyl ethers, this cleavage also represents a key model reaction for the liquefaction of coal; thus this catalyst system and process should be useful in coal liquefaction with the advantage of operating at significantly lower temperatures and pressures.

Aqueous high-temperature chemistry of carbo- and heterocycles. 2. Monosubstituted benzenes: Benzyl alcohol, benzaldehyde, and benzoic acid

Journal Article Katritzky, A R ; Balasubramanian, M ; Siskin, M

Benzyl alcohol is not very reactive under aquathermolysis conditions, except in the presence of acids. Almost all the products are formed by ionic pathways. It undergoes reversible dehydration to dibenzyl ether, disproportionation to benzaldehyde and toluene, and self-benzylation to 2- and 4-benzylbenzyl alcohols. These benzylbenzyl alcohols can react further, but major amounts of polyalkylated products are formed by the mono- and dibenzylation of toluene to give a range of dibenzyltoluenes and (benzylbenzyl)toluenes. Small amounts of diphenylmethane and bibenzyl and their benzylated products are also formed. The behavior of benzyl alcohol in the presence of phenol, pyridine, benzaldehyde, and benzene ismore »« less

Cleavage of dibenzyl ether in the presence of zinc halides

Journal Article Frederick, T J ; Bell, A T - J. Catal.; (United States)

The large amount of water liberated during coal liquefaction in the presence of ZnCl/sub 2/ is believed to derive from the cleavage of benzylic ethers. The details of this process have been studied using dibenzyl ether as a model structure and ZnCl/sub 2/, ZnBr/sub 2/, and ZnI/sub 2/ as catalysts. The influence of H/sub 2/O and HX on the progress of the reaction was also examined. In the absence of HX addition, ZnX/sub 2/ activates the ether by forming a Lewis acid-base complex with it. Water interferes with the formation of this complex by competing for ZnX/sub 2/. In themore »« less

Coal liquefaction model studies: free radical chain decomposition of diphenylpropane, dibenzyl ether, and phenyl ether via. beta. -scission reactions

Journal Article Gilbert, K E ; Gajewski, J J - J. Org. Chem.; (United States)

The thermal decompositions of 1,3-diphenylpropane (1), dibenzyl ether (2), and phenethyl phenyl ether (3) have been found to proceed by free radical chain processes. 1 gave toluene and styrene with a reaction order of 1.55, E/sub A/ = 51.4 kcal/mol, and log A = 12.5. The reaction could be initiated by benzyl phenyl ether but not by 1,2-diphenylethane. 2 gave toluene and benzaldehyde with a reaction order of 1.43, E/sub A/ = 48 kcal/mol, and log A = 12.6. The reaction could be initiated with benzyl phenyl ether. 3 gave phenol and styrene with a reaction order of 1.21, E/submore »« less

Studies of the initial reactions that occur during direct coal liquefaction

Conference Stohl, F V

Reactions that occur during preconversion processing of coal in direct liquefaction can be either beneficial or harmful. The objectives of this work are to identify the types of compounds and process conditions that give rise to retrogressive reactions during preconversion processing. Experiments have been performed to evaluate the impacts of temperature, catalysts, mineral matter, and hydrogen donors on these reactions. Initial studies have been carried out using dibenzyl ether (DBE) because ether linkages represent one type of bonding believed to be present in coal (1). Previous studies have analyzed the kinetics and mechanisms of thermolysis of DBE (2,3) and havemore »« less
