Purification of tetrahydrofuran

A process for purifying tetrahydrofuran which comprises:

• intimately mixing the tetrahydrofuran to be treated at from room temperature to the boiling point of the tetrahydrofuran with a bleaching earth containing less than 3% by weight of water for from 3 minutes to 12 hours, and thereafter separating the bleaching earth from the tetrahydrofuran, whereby the carbonyl number, the bromine number and the peroxide content of the tetrahydrofuran are reduced.
