- W2389741982 abstract "Etherification of ethanol and tert-butyl alcohol to ETBE(ethyl tertiary butyl ether),using USY zeolite midified by hydrofluoric acid as the catalyst,was studied.The solid acid catalyst showed superior catalytic properties to those of D005 strong acidic cation exchange resins and unmodified USY zeolite for synthesis of ETBE.Influence of reaction temperature,reaction time and dosage of HF on the reaction was investigated.The optimum condition was obtained as follows: n(ethanol)∶n(tert-butyl alcohol)=2∶1,m(feed)=10 g,m(catalyst)=1 g,loadings of HF on USY zeolite=6%,reaction temperature 120 ℃,reaction time 3 h.Tert-butyl alcohol conversion of 55.83%,selectivity to ETBE of 95% and ETBE yield of 52.46% were attained under the optimum condition." @default.
