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: Formamide is manufactured continuously from methyl formate and gaseous ammonia. The reaction is carried out in a reactor at from 30 to 90 DEG C, from 5 to 20% by volume of the reactor output is drawn off continuously and fed to the formamide working-up stage, and the remainder of the reactor output is cooled, in an external circuit maintained by means of a pump, to from 25 to 60 DEG C and is mixed with the amount of fresh methyl formate required for steady-state operation, after which the appropriate amount of gaseous ammonia is introduced into the stream of liquid through a jet, by the sucking-jet principle, and the stream of liquid is recycled to the reactor.

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.
