Abstract: A process is proposed for the separation of C 5+ cuts by distillation into a low-boiler (A), a medium-boiler (B) and a high-boiler fraction (C) in one or more dividing-wall columns (TK), in which a dividing wall (T) is arranged in the longitudinal direction of the column with formation of an upper, common column region ( 1 ), a lower, common column region ( 6 ), a feed part ( 2, 4 ) with rectifying section ( 2 ) and stripping section ( 4 ), and a withdrawal part ( 3, 5 ) with rectifying section ( 5 ) and stripping section ( 3 ), with feed of the C 5+ cut (A, B, C) into the central region of the feed part ( 2, 4 ), discharge of the high-boiler fraction (C) from the bottom of the column, discharge of the low-boiler fraction (A) via the top of the column, and discharge of the medium-boiler fraction (B) from the central region of the withdrawal part ( 3, 5 ), wherein the dividing ratio of the liquid reflux at the upper end of the dividing wall (T) is set in such a way that the proportion of high-boiling key components in the liquid reflux over the stripping section ( 3 ) of the withdrawal part at the upper end of the dividing wall (T) is from 10 to 80%, preferably from 30 to 50%, of the limit value allowed in the medium-boiler fraction (B), and wherein the heating power in the evaporator at the bottom of the dividing-wall column (TK) is set in such a way that the concentration of the low-boiling key components in the liquid at the lower end of the dividing wall (T) is from 10 to 80%, preferably from 30 to 50%, of the limit value allowed in the medium-boiler fraction (B).

Abstract: Production of propionic acid (or its ester) from acrylic acid (or its ester) comprises: (1) partial dehydrogenation of propane to give a mixture (A); (2) partial oxidation of propylene in (A) to form a mixture (B); and (3) hydrogenation of the acrylic acid in (B) (directly and/or after esterification) to form a mixture (C). At least part of the hydrogen used in step (3) is that formed in step (1). Production of propionic acid (or its ester) from acrylic acid (or its ester) comprises: (1) heterogeneously catalyzed partial dehydrogenation of propane in a first reaction zone, to give a product gas mixture (A) containing molecular hydrogen, propylene and unconverted propane; (2) charging the propylene in (A) to a second reaction zone, in which the propylene is subjected to selective, heterogeneously catalyzed partial gas phase oxidation with molecular oxygen to form a product gas mixture (B) containing acrylic acid; and (3) charging the acrylic acid in (B) (directly and/or after esterification) to a third reaction zone, in which the acrylic acid (or ester) is hydrogenated with molecular hydrogen to form a product gas mixture (C) containing propionic acid and/or its ester. At least part of the hydrogen used in step (3) is that formed in step (1).
