摘要： Bromide source such as alkali metal bromide, alkaline earth metal bromide, or onium bromide, present as part of a catalyst mixture in an organic oxidative carbonylation mixture further comprising diaryl carbonate and a hydroxyaromatic compound, is often at least partially converted to organic bromide such as bromophenols. The bromide source can be recycled after reaction through treatment with an aqueous acidic bromide solution such as hydrogen bromide, preferably after removal of a major proportion of hydroxyaromatic compound such as phenol.

摘要： A process for catalytic production of diaryl carbonates by oxidative carbonylation of aromatic hydroxy compounds with carbon monoxide and oxygen achieves water removal during reaction by a process comprising the steps of: removing a liquid stream from an oxidative carbonylation reaction mixture in a reaction vessel, subjecting the liquid stream to reduced pressure, and returning at least a portion of dried liquid stream to the reaction vessel. Typical catalyst systems for oxidative carbonylation contain (A) at least one Group 8, 9, or 10 metal having an atomic number of at least 44 or a compound thereof; (B) at least one alkali metal salt; (C) at least one metal co-catalyst; (D) at least one activating organic solvent; and (E) optionally, at least one base.

摘要： A process for catalytic production of diaryl carbonates by oxidative carbonylation of aromatic hydroxy compounds with carbon monoxide and oxygen achieves water removal during reaction by a process comprising the steps of: removing a liquid stream from an oxidative carbonylation reaction mixture in a reaction vessel and transferring the stream to a disengagement vessel, transferring a stream from the disengagement vessel to a flash vessel and subjecting the liquid stream to reduced pressure, and returning at least a portion of dried liquid stream to the reaction vessel. Typical catalyst systems for oxidative carbonylation contain (A) at least one Group 8, 9, or 10 metal having an atomic number of at least 44 or a compound thereof; (B) at least one guanidinium salt or onium salt; (C) at least one metal co-catalyst; and (D) at least one base.
