Process for the production of diaryl carbonates from carbonyl halide with recycling of at least some of the hydrogen halide byproduct and reactor therefor. |
摘要 |
<p>A process for the production of a diaryl carbonate comprising: contacting an aromatic hydroxy compound or a mixture thereof and its haloformate derivative with a carbonyl halide in the presence of a catalyst in a reactor system under conditions sufficient for the formation of a diaryl carbonate and a hydrogen halide; recovering the aromatic carbonate; and recycling at least some of the hydrogen halide within the reactor system to regenerate the carbonyl halide. <IMAGE></p> |
