Abstract: Hydroformylation of olefinically unsaturated compounds by means of triorganorhodium (rhodium/triorganyl) complexes at 80 to 140 DEG C and 10 to 40 bar by using for this purpose a cylindrical reactor (1) - see figure - equipped with an axially arranged nozzle (2) for introduction of the olefinic compound and the synthesis gas consisting of H2 and CO, a valve (3) for discharging the material and a concentric tube (4) whose height is about 20 to 70 % of the reactor height and whose diameter is about 30 to 80 % of the reactor diameter and which is arranged above the nozzle (2) at a distance of about 1 to 3 times its diameter, the momentum of the gases entering through (2) being such that the mean linear flow rate of the liquid reactor contents is 0.1 to 1.0 m/sec.

Abstract: Dimethyl carbonate is obtained pure, from its solutions in methanol, by extractive distillation carried out with a temperature of from 60 DEG C. at the top to 250 DEG C. at the bottom of the column and employing, as the extractant, an aprotic organic liquid which is substantially inert toward dimethyl carbonate, boils at above 100 DEG C. at standard pressure, is miscible with dimethyl carbonate in all proportions and has a dielectric constant epsilon of from 4 to 90 and a dipole moment mu of from 1.5 to 5 Debye.

Abstract: Aldehydes are obtained from the gaseous product of the hydroformylation of olefinically unsaturated compounds using a rhodium catalyst by a process (cf. FIG. 2) in which (a) this gaseous product is introduced, without being cooled or depressured, into a distillation column D, (b) the top fraction from this column is cooled in a condenser K so that the greater part of the aldehydes contained therein is condensed, (c) the condensate is separated, in a separator A, into a gas phase and a liquid phase, (d) the gas phase from A, after waste gas has been separated off, is again brought to the hydroformylation pressure by means of a compressor P, and is returned to the reactor as a recycle gas, (e) the liquid phase from A is returned to D, and (f) the aldehydes are taken off from column D as liquid bottom products and/or as a vaporous side stream.

Abstract: Hydroformylation of propylene with simultaneous operation by the high-pressure process using cobalt catalysts and the low-pressure process using rhodium catalysts, by employing the waste gas, which still contains considerable amounts of unreacted propylene, CO and H2, obtained from the high pressure plant after the removal of cobalt from the reaction mixture, again in the low-pressure plant.
