Abstract: The invention relates to a base for a mass transfer column, comprising gas through-openings which are distributed over the base (1) and at least one baffle plate (11) for directing the flow of liquid flowing on the base, said base (1) being loadable with a liquid via at least one inlet (3). The base has at least one inlet (3), at least one separating weir (5) which separates the inflowing liquid into two flows, and at least two outlets (12) or at least two inlets (3) and at least one outlet (12) for the liquid. Each flow flows along a flow path (7; 9) to an outlet (12). The invention further relates to a mass transfer column which contains the base and to a use of the base and the mass transfer column.

Abstract: The invention relates to a method for producing phthalic anhydride that conforms to specifications in a purification of crude phthalic anhydride by distillation at a reduced pressure. According to said method, the crude phthalic anhydride is supplied to the distillation column above a lateral outlet, the low-boilers are drawn off at the head of the column or in the vicinity of the head of the column and the phthalic anhydride that conforms to specifications is removed from the lateral outlet. The method uses a distillation column with a number of theoretical separation stages situated above the supply of the crude phthalic anhydride to the distillation column that lies between 10 and 20 and the column operates with a reflux ratio of between 0.1 and 0.5.
