Solvent effects in the depolymerization of coal

The depolymerization reaction of coal in the presence of Friedel-Crafts catalysts in a variety of phenolic and non-phenolic solvents has been investigated. Only the phenolic solvents were found to be useful in this reaction. Some interesting substituent effects were discovered when the isomeric cres...

Description
Summary:The depolymerization reaction of coal in the presence of Friedel-Crafts catalysts in a variety of phenolic and non-phenolic solvents has been investigated. Only the phenolic solvents were found to be useful in this reaction. Some interesting substituent effects were discovered when the isomeric cresols and dihydroxybenzenes were employed as solvents. The influence of temperature and catalyst concentration on the degree of depolymerization has also been examined. With non-phenolic solvents, polymerization is the predominant reaction.
