HYDROFORMYLIERUNG EINES MEHRKOMPONENTENEINSATZSTROMES
摘要
A process for the production of C3 to C6 aldehydes by hydroformylating a mixture of (i) C2 to C5 olefins and mixtures thereof, (ii) C2 to C5 alkynes and mixtures thereof and optionally (iii) cumulated dienes in the presence of a solution of a rhodium organophosphorus complex catalyst at a concentration of rhodium in solution of from 1 to 1000 ppm by weight, in particular the olefine is ethylene and the alkyne acetylene and the ratio of phosphorus to rhodium is greater than 30. The aldehydes are useful intermediates in the production of various alcohols, polyols and acids.
