Catalyst composition and method for producing diaryl carbonates, using bisphosphines |
| abstract |
Hydroxyaromatic compounds such as phenol are carbonylated with oxygen and carbon monoxide in the presence of a catalyst system comprising a Group VIIIB metal, preferably palladium; an iodide salt, preferably sodium iodide; and at least one organic bisphosphine such as 1,3-bis(diphenylphosphino)propane or 1,4-bis(diphenylphosphino)butane. The catalyst system also preferably contains a compound of cerium or lead. |
