Title: Catalytic Reaction of Phenol and Tert-butanol With Sulfonated Asphalt as Catalyst
Abstract: Asphalt modified by sulfonation as a new,cheap,efficient and environment-friendly solid acid catalyst was applied in alkylation of phenol and tert-butanol.Catalytic activity was investigated,and effect of phenolic/alcohol molar ratio,catalyst amount,reaction temperature,reaction time,etc.on phenol conversion,product selectivity and reusability of the catalyst was studied.The optimum reaction conditions were determined as follows: T = 70 ℃,t = 360 min,n(TBA)/ n(Phenol)=2︰1,catalyst dosage 0.6 g.Under these conditions,phenol conversion rate can reach 75.8%.
