Abstract
έθοδος προς αφυδάτωσιν αλκοολών τη βοηθεία της αζεοτροπικής αποστάξεως, χαρακτηριζομένη ε του ότι ως αφυδωτικά μέσα χρησιμοποιούνται τοιαύτα άκρατα υγρά, π.χ. τριχλωριαιθυλένιον, τα οποία κατά τον εις στοιβάδας διαχωρισμόν (απόχυσιν) του τριαδικού μίγματος, παραμένουν εν τη υδαρεί στοιβάδι εις τόσον μικράς ποσότητας, ώστε καθίσταται δυνατή η άμεσος ενδυνάμωσις της ενύδρου αλκοόλης της υδαρούς στοιβάδας.method for dehydrating alcohols with the aid of azeotropic distillation, characterized in that such extreme liquids are used as dehydrating agents, e.g. trichloroethylene, which during the layer separation (pouring) of the tertiary mixture, remain in the aqueous layer in such a small amount that it is possible to directly strengthen the hydrated alcohol of the aqueous layer.
