Olefin hydroformylation methods for obtaining branched aldehydes |
| abstract |
The present technology relates to methods of hydroformylating allyl alcohol to 4-hydroxybutanal and 2-methyl-3-hydroxypropanal, comprising (i) admixing allyl alcohol with CO and H 2 to form a starting material mixture, and (ii) reacting the starting material mixture in the presence of a catalyst under conditions capable of forming a product mixture comprising 4-hydroxybutanal and 2-methyl-3-hydroxypropanal, wherein the catalyst is a transition metal complex comprising a transition metal ion and a diphosphine ligand with a bite angle from about 70° to about 100°, and wherein the ratio of 4-hydroxybutanal to 2-methyl-3-hydroxypropanal in the product mixture is less than 1.5:1. |
