Method for the catalytic preparation of aldehydes from olefins using monophosphite mixtures

Abstract

The catalytic preparation of an aldehyde from an olefin proceeds in the presence of a monophosphite mixture.

Description

technical field [0001] The present invention relates to a process for the catalytic preparation of aldehydes from olefins by using monophosphit mixtures and to the novel monophosphit mixtures themselves. Background technique [0002] The reaction between olefinic compounds, carbon monoxide and hydrogen in the presence of a catalyst to form an aldehyde with one more C atom is known as hydroformylation or oxo synthesis. Compounds of transition metals from Group VIII of the Periodic Table of the Elements are generally used as catalysts in this reaction. Known ligands are, for example, each with trivalent phosphorus P III Phosphine, phosphite and phosphonite classes of compounds. A good overview of the prior art on the hydroformylation of olefins exists in B. CORNILS, W.A. HERRMANN, "Applied Homogeneous Catalysis with Organometallic Compounds", Volumes 1 & 2, VCH, Weinheim, New York, 1996 or R. Franke, D. Selent, A.B Örner, "Applied Hydroformylation", Chem.

Problems solved by technology

However, this has the disadvantage that both ligand types are very expensive in their preparation, and therefore an industrial large-scale process can hardly be economical
