PROCEDIMIENTO PARA LA HIDROFORMILACION DE COMBINACIONES NO SATURADAS DE OLEFINAS

EL GAS DE ESCAPE QUE SE FORMA EN LA HIDROFORMILACION DE COMPUESTOS INSATURADOS OLEFINICOS EN PRESENCIA DE UNA SOLUCION ACUOSA E HIDROSOLUBLE DE CATALIZADOR QUE CONTIENE COMPUESTOS DE COMPLEJOS DE RODIO (1 SISTEMA DE REACCION HOMOGENEO EN EL QUE TRANSFORMAN CANTIDADES RESIDUALES DE LOS COMPUESTOS INSATURADOS OLEFINICOS DE LA 1 TAPA DE LA REACCION EN UN SISTEMA DE REACCION HOMOGENEO (2 APA DE REACCION). Hydroformylation of olefinically unsaturated compounds is carried out as follows. (a) The olefinic compounds are reacted in a heterogeneous reaction system with an aqueous solution containing water-soluble complexes of rhodium compounds and organic phosphorus (III) compounds as catalysts, at 0.4-10 MPa; and (b) the exhaust gas produced is subjected to a second reaction, in which residual olefinically unsaturated compounds still present in the gas are converted in a homogeneous reaction system in the presence of complex compound of Rh with organic P(III) compounds as catalysts at 15-40 MPa.
