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: Reaction mixtures which are obtained on hydroformylation or carbonylation of olefinically unsaturated compounds and which contain dissolved non-volatile complex compounds of metals of group VIII of the periodic table are worked up by a method wherein the products, after distillative removal of low-boiling constituents alone, or of these constituents plus a part of the high-boiling residue, or a part of the high-boiling residue after distillative removal of the desired products, are or is extracted with carbon dioxide, a C2-C4-paraffin, a C2-C4-olefin or a normally gaseous halohydrocarbon at above the critical temperature and above the critical pressure of these (extractant) compounds.

Abstract: Hydroformylation of olefinically unsaturated compounds, using rhodium triarylphosphine catalyst, by using those catalysts of this type in which the triarylphosphine corresponds to the general formula I in which at least one of the radicals R denotes an m-fluorophenyl, m-chlorophenyl, p-methoxycarbonyl or p-trifluoromethyl group and the remaining radicals denote the phenyl group.

Abstract: A process for hydroformylating olefinically unsaturated compounds by means of rhodium/triphenylphosphine/carbonyl complexes formed in situ from rhodium acetate, triphenylphosphine and carbon monoxide, wherein the hydroformylation reaction is preceded by a starting phase in which the mixture of the hydroformylation medium, the triphenylphosphine and rhodium acetate is heated at from 90 DEG to 120 DEG C. under a CO/H2 pressure of from 5 to 20 bar and the acetic acid liberated is discharged from the reactor in gaseous form in a stream of CO and H2, until virtually no more acetic acid can be detected in this gaseous discharge.

Abstract: In the removal and opt. recovery of O2 from gas by treatment with phosphine complexes with Mn (II) halides, the gas, if moist, is predried. Drying prevents an irreversible change, so that the complex retains a large fraction of its activity and can be used for continuous exchange. The complexes are useful for sepg. O2 from air in confined spaces, e.g. ships and aircraft, for removing traces of O2 from gases and esp. as detectors for the O2 content of gases, since they are intensely coloured when combined with O2 and colourless to pale yellow when free from O2. In an example, air was passed into 10 g 9 wt.% soln. of the dimethylphenylphosphine-Mn (II) bromide complex in THF at 20 deg.C and normal pressure. The soln. was yellowish initially and became intensely coloured very rapidly. If 2 ml water were added, the colour disappeared immediately and the O2 binding complex was destroyed. If O2 was introduced again, it was no longer bound. If 60 ml BuOH were added, the complex was destroyed within 15 min.

Abstract: Aldehydes are prepared by hydroformylating the corresponding olefinically unsaturated compounds with the aid of rhodium-carbonyl complexes which contain tertiary phosphines as ligands, by carrying out the reaction in the presence of compounds of copper, silver or zinc which are soluble in the reaction mixture and do not contain any component which deactivates the rhodium-carbonyl complexes.
