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: O. Z. OO5O/35O76 Aldehydes are obtained from the gaseous product of the hydroformylation of olefinically unsaturated compounds using a rhodium catalyst by a process (cf. Figure 2) in which a) this gaseous product is introduced, without being cooled or let down, 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 separa ted off, is again brought to the synthesis 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: Methyl formate is prepared by reaction of carbon monoxide and methanol at elevated pressure and elevated temperature in the presence of an alkali metal methoxide by A) mixing the starting substances in a mixing zone, partially allowing them to react, saturating the reaction solution with CO and B) carrying the reaction to completion in one or more subsequent reaction zones without addition of further starting compounds.

Abstract: O.Z. 32,004 Formamide is manufactured continuously from methyl formate and gaseous ammonia. The reaction is carried out in a reactor at from 30 to 90.degree.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.degree.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.
