An improved Procedure of primary hidroformilacion, to produce aldehydes.

摘要

Improved procedure for Primary hidroformilar Olefins to produce aldehydes.Consists in reacting an olefin, carbon monoxide and Hydrogen in the presence of a soluble Rhodium Complex Catalyst with phosphorus - Phosphorus ligands and aldehyde condensation by-products of high Boiling Point and eliminate the process a gaseous effluent that contains OLEF Ina unreacted aldehyde, any of the listed Products, h,And a by-product of alkane. The Improvement consists in performing a secondary hidroformilacion catalyzed by Rhodium, recirculating liquid or gas together with the primary process using the effluent together with co and H replacement, such as food of the secondary process.
