METHOD FOR RECYCLE OF BROMIDE-CONTAINING CATALYST CONSTITUENTS |
摘要 |
<p>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.</p> |
