Definitions
- the present invention relates to a process for the hydrocyanation of an olefinically unsaturated nitrile in the presence of a Ni (0) -containing catalyst, characterized in that the reaction is carried out in the presence of a hydrocarbon which, under certain pressure, concentration and temperature conditions, forms at least two leads liquid phases of the overall system, of which one phase has a higher proportion of the Ni (0) -containing catalyst, based on the total weight of this phase, than the other phase or other phases.
- US Pat. No. 3,773,809 describes the hydrocyanation of 3-pentenenitrile or 4-pentenenitrile in the presence of a catalyst system composed of Ni (0) and a ligand system complexing it, comprising, on the one hand, monophosphines or onophosphites and, on the other hand, a nitrile, and further compounds as catalyst promoters.
- a catalyst system composed of Ni (0) and a ligand system complexing it, comprising, on the one hand, monophosphines or onophosphites and, on the other hand, a nitrile, and further compounds as catalyst promoters.
- a hydrocarbon is added to the product mixture obtained under defined conditions in an extractor, a multi-phase system being formed.
- One phase of this multiphase system contains the hydrocarbon and the major part of the organophosphorus compounds mentioned and the Ni (0) complexes, while organic mononitrile, organic dinitrile, decomposed Ni catalyst, decomposed organophosphorus compound and catalyst promoter essentially in another phase are included.
- the hydrocarbon phase is separated off.
- organic mononitrile, organic dinitrile and catalyst promoter are separated from the decomposed nickel catalyst and the decomposed organophosphorus compound.
- this separation by distillation has the problem that, on the one hand, in order to avoid thermal decomposition of the catalytically active compounds contained in the hydrocarbon phase, the lowest possible distillation temperature is desirable, as can be achieved, for example, by lowering the pressure; on the other hand, in technical distillations, it is desirable to use river water for counter-cooling, that is to say for condensing the distillate. This in turn places limits on reducing the distillation pressure.
- the present invention had for its object to provide a process which separates the catalyst used in the hydrocyanation of an olefinically unsaturated nitrile, which contains Ni (0), from the product and unreacted starting material, preferably with the possibility of reusing the above Catalyst, especially in the hydrocyanation mentioned, made possible in a technically simple and economical manner.
