A process for preparing high-purity phytantriol

A process for preparing high-purity phytantriol, which is characterized in that the metal fabric packaging with an ordered structure using channel liquid distributors with resulting low and / or higher-boiling by-products contaminated phytantriol in a high vacuum containing in rectification columns equal to or more than 500 drip points / m 2 · which are arranged at an angle of 90 ° to the cloth layers of the packing elements located directly below the distributors, in which 2 or more packing elements underneath the liquid distributors only have a low height to ensure an absolute exclusion of air and strict adiabatic manner rectified. DOLLAR A Especially advantageous is the preparation of high purity phytantriol designed when used as contaminated with by-products Phytantriol a phytantriol which has been obtained by reacting isophytol with performic acid and subsequent hydrolysis of the reaction product formed with alkaline agents in a known manner.
