A novel method of synthesizing ethyl t-butyl ether (ETBE). A C4 ingredient consisting mainly of isobutene (IB), e.g., a C4 ingredient pressurized and liquefied at ordinary temperature, and hydrous ethanol (EtOH) which is a product of the rectification of bioethanol are used as raw materials. A reactor (reaction column) (14) having a fixed-catalyst reaction stage (22) is used to stoichiometrically react IB in a liquid phase with EtOH and water under mild conditions including a medium pressure (1,000 kPa or lower) and a medium temperature (100°C or lower) to synthesize ETBE and t-butyl alcohol (TBA). |
