High linear selectivity ligand for allyl alcohol hydroformylation and process to produce 4-hydroxybutyraldehyde |
| abstract |
A process for selectively producing 4-hydroxybutyraldehyde from allyl alcohol is described. The process comprises reacting allyl alcohol with a mixture of carbon monoxide and hydrogen in the presence of a solvent and a catalyst system comprising a rhodium complex and a trans-1,2-bis(bis(3,4,5-tri-n-alkylphenyl)phosphinomethyl)-cyclobutane. The process gives high yield of 4-hydroxybutyraldehyde compared to temperature. |
