The invention relates to the field of inorganic chemistry, in particular to the types of the sieve trays and distillation column can be used for purifying titanium tetrachloride by distillation. Technical result is directed to overcome the drawbacks of the prototype and allows by increasing the rate of passage of vapor and gas mixture, reducing the particulate matter deposits in the hole plates reduce equipment wear and thus maintenance costs for the distillation column and to increase its productivity. Technical result is achieved by the proposed sieve tray distillation column, comprising a housing in which a flat perforated plate with the same diameter holes overflow device for a liquid and a water seal, new is the fact that it is further provided with chamfers made in the form of a cone at each orifice flat sheet from above and below at a ratio of the upper diameter to the diameter of the chamfer cone holes to be (1.4-1.6): 1.
