Preparation of methyl formate by the reaction of carbon monoxide and methanol under conditions of elevated pressure and temperature in the presence of an alkali metal methylate, in which

Preparation of methyl formate

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

Recovery of aldehydes from hydroformylation reaction gas

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.
