O-Ethylation of Catechol and Ethanol on Al-P-Ti-Si-O Catalyst

Abstract

Abstract: The catalysts of Al-P-Ti-Si-O were prepared by common precipitation method. Vapor phase O-ethylation of catechol with ethanol over the synthesized samples was studied. The activity and selectivity of these catalysts were greatly dependent on the compositions. In addition, the compositions affect the phase structure, surface properties and acidity of the catalysts. Brnsted acid site is the possible active site. During being tested for 100 h, the conversion of catechol and the yield of guathol maintained about 94% and 84%, respectively 96% and 90% at the optimized conditions.

Key words: Catechol, Guathol, Ethanol
