ABSTRACT:
There is disclosed a process for continuously producing diisopropyl ether of high purity from isopropyl alcohol and propylene at a high yield, which comprises the steps of: continuously passing isopropyl alcohol and propylene at a given molar ratio through a first fixed bed filled with particles of strongly acidic cation-exchange resin at a temperature in the range from 100.degree. C. to 130.degree. C.; then passing the reaction mixture through a second fixed bed filled with a water-insoluble, solid, particulate acid-neutralizing agent; and flash-removing unreacted propylene from the mixture, followed by solvent refining and distillation, whereby diisopropyl ether of high purity is continuously obtained at a high yield.
