Abstract
Improvements in the process for the manufacture of extraneutral alcohol object of the main patent characterized in that the liquid contained in the upper part of the scrubbing column is led to a resting zone, the water destined for watering is introduced into said resting zone. To cause the separation of said liquid in a topical layer in impurities of the amyl alcohol type and in an aqueous lower layer which is sent again under the underlying plate by subjecting to a distillation the vapors extracted at the head of the purification column with object to separate from them the head impurities that are extracted at the desired speed and the residual liquid from said distillation is sent to the resting zone of the purification column.
