Abstract
A process for the purification of olefine oxides by subjecting a mixture containing the olefine oxides to distillation in a distillation column in the presence of a small amount of water in order to obtain olefine oxide as the distillate. A fraction of the down-flow liquid is withdrawn from the column and the withdrawn fraction is subjected to decantation, so as to separate off an aqueous phase which is discarded, and an organic phase. The organic phase is returned to the column at a point located below the withdrawal point.

In a process for the purification of olefine oxides by subjecting a mixture containing the olefine oxide to distillation in a distillation column in the presence of a small amount of water, so as to obtain the olefine oxide as the distillate, the improvement comprises withdrawing a fraction of the liquid flowing down through the column from the column, subjecting the withdrawn fraction to decantation so as to separate off an aqueous phase, which is discarded, and an organic phase, and returning the organic phase to the column at a point located below the withdrawal point.
