    Abstract: A substituted indanole of formula (I) is prepared by reacting a substituted indanone of formula (II) with a base and water in the presence of a metal or metal-oxide catalyst. A substituted indanole of formula (I) is prepared by reacting, in the presence of a catalyst comprising, on a substrate, a group VIII metal or its oxide, at 10 - 100 bar pressure and 30 - 200 [deg]C, a substituted indanone of formula (II) with a base and water. The reaction is carried out in an organic solvent, wherein up to 50 weight. % water, based on the amount of solvent, is present. The base comprises 0.1 - 1.3 mole, based on 1 mole indanone of formula (II). [Image] R1> - R7>H, halogen, 1 - 20C alkyl, 6 - 14C aryl, 1 - 10C alkoxy, 2 - 10C alkenyl, 7 - 20C arylalkyl, 7 - 20C alkylaryl, 5 - 10C aryloxy, 1 - 10C fluoroalkyl, 6 - 10C haloaryl or -SiR8>3; R8>1 - 10C alkyl; and two or more of R1> - R8> may bond to form optionally substituted rings.

    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: The invention relates to a method for carrying out the distillative separation of C5+ cuts into a low boiler fraction (A), a medium boiler fraction (B) and into a high boiler fraction (C) inside one or more partition columns (TK). A partition (T) is arranged inside said partition column(s) in a longitudinal direction of the column(s) while forming an upper common column area (1), a lower common column area (6), a feed part (2, 4) having a reinforcing part (2) and stripping part (4), as well as while forming a withdrawal part (3, 5) also having a reinforcing part (5) and stripping part (3). The inventive method involves the following steps: supplying the C5+ cuts (A, B, C) in the middle area of the feed part (2, 4); discharging the high boiler fraction (C) out of the bottom of the column; discharging the low boiler fraction (A) via the top of the column, and; discharging the middle boiler fraction (B) out of the middle area of the withdrawal part (3, 5). The dividing up ratio of the liquid reflux at the upper end of the partition (T) is set such that the proportion of high-boiling key constituents in the liquid reflux above the stripping part (3) of the withdrawal part at the upper end of the partition (T) ranges from 10 to 80 %, preferably, from 30 to 50 % of the limiting value permitted in the middle boiler fraction (B). In addition, the heating capacity in the bottom evaporator of the partition column (TK) is set such that the concentration of the light-boiling key constituents in the liquid at the lower end of the partition (T) ranges from 10 to 80 %, preferably, from 30 to 50 % of the limiting value permitted in the middle boiler fraction (B).
