Abstract

A process for the hydration of olefins to prepare alcohol is disclosed, the hydration being effected in the presence of a phosphorus acid-containing catalyst. There is disclosed a process in which vaporized phosphoric acid is admixed with a gas mixture before the same is added to the reactor, the phosphoric acid being in an amount corresponding to the amount of phosphoric acid discharged during the hydration. In such amount the process can be carried out without further phosphoric acid addition.
