Production method
1. The dehydration temperature is 140-150 ℃. Benzenesulfonic acid can also be used instead of sulfuric acid. In addition, the addition compound of boron trifluoride and alcohol is heated; n-propanol can be subjected to gas phase dehydration at 200°C under the action of a nickel catalyst on magnesium oxide to prepare propyl ether. 2. n-propanol is dehydrated at 200 ℃ under the action of nickel catalyst on magnesium oxide to obtain propyl ether.
