The dehydration of ethanol, 1-propanol and 1-butanol has been studied at atmospheric pressure using the novel microporous niobium silicate AM-11 (Aveiro–Manchester structure number 11) in the temperature range 150–300 °C. The selectivity for alkenes increases with temperature for all three alcohols and reaches 100% for 100% conversion at 250–300 °C. At lower reaction temperatures (∼200 °C), ethers are also formed and their selectivity decreases markedly with the alcohol size.
