Vapor-phase reactions of catechol with dimethyl carbonate. Part IV: Synthesis of catechol carbonate over alumina loaded with cesium hydroxide Original Research Article

Catechol carbonate was synthesized by the vapor-phase reaction of catechol with dimethyl carbonate over alumina loaded with CsOH (CsOH/Al2O3). The yield of catechol carbonate was 50% at 88% catechol conversion at 583 K, the main side product being guaiacol. The effects of the reaction variables on the yield of catechol carbonate were examined.
