Photostabilization of an epoxy resin by forming interpenetrating polymer networks with bisphenol-A diacrylate. -Substituted Benzylanilines. Palladium-catalyzed synthesis of benzyl esters from methyl-benzenes. Its formation is reversible, unlike that of the ortho isomer which is stabilized by chelation. The o-isomer is separated from the mixture by steam-distillation.Generally low temperature (60°C or less) favours the formation of the p-isomer whereas high temperature (above 160°C) favours the o-isomer. The para isomer (rate-controlled product) is the exclusive product at 25°C because it has a lower ΔH and is formed more rapidly. Copyright © 2020 Entrancei. The ortho isomer is separated from the mixture by its volatility with steam.The phenyl ester formed from the reaction of phenol and acid anhydride undergoes rearrangement when treated with anhydrous AlCl3 to yield ortho and para-hydroxyketones.

Edoardo Torti, Gioia Della Giustina, Stefano Protti, Daniele Merli, Giovanna Brusatin, Maurizio Fagnoni. Although it has a higher ΔH, the ortho isomer (equilibrium-controlled product) is the chief product at 165°C because it is more stable.
