Phospho knight content catalyst null i. general formula (i)

摘要

Discloses a catalyst solution for the preparation of aldehydes having an aldehyde ratio - aldehyde to iso - comprising phosphonite more ligands, the hydroformylation solvent and rhodium, or various normal one. Also, comprising a phosphonite that more ligands, is contacted with the hydroformylation solvent and one or rhodium, olefin, hydrogen and carbon monoxide, various normal - aldehyde with aldehyde ratio - iso aldehyde to I also disclosed a manufacturing method. By varying the process variables more or one including the partial pressure of carbon monoxide, the ligand and temperature (gram moles) to rhodium (gram atom), a catalyst solution as a base material phosphonite, n - aldehyde to It is possible to manipulate the aldehyde ratio - iso.
