摘要：
The oxidation of ethane to ethanol and methanol has been studied at 34 atm. The best result obtained was the total alcohol selectivity of 57% at ethane conversion of 6.2%. The liquid collected contained 37% of methanol and 17% of ethanol. The effect of reaction variables on product distribution and alcohol selectivity and the effect of pre-heater have been examined. The selectivity for ethanol was particularly sensitive to reaction parameters, while the selectivity of methanol formation of 25-30% has been found for wide range of reaction conditions. At high temperatures the transition to oxidative coupling of ethane with n-butane formation as the major product (selectivity up to 33%) was observed. Due to the formation of alcohols and butane the process studied has the potential for the production of octane enhancers such as MTBE and ETBE. (C) 1998 Elsevier Science B.V. AU rights reserved.
