| 摘 要： | 研究了新型的Ｐｄ－Ｃｏ催化体系催化氧化碳化苯酚合成碳酸二苯酯。当ｎ（ＰｄＣｌ２）：ｎ「Ｃｏ（Ⅱ）」：ｎ（四丁基化铵）：ｎ（苯醌）＝１：１：１０：２５，Ｔ＝１２０，Ｐ＝２．５ＭＰａ（Ｐｃｏ／Ｐｏ２＝４：１），反应时间８ｈ，ＰｄＣｌ２－Ｃｏ（Ｐｙｃａ）２比ＰｄＣｌ２－Ｃｏ（ＯＡｃ）２的催化活性高。当使用ＰｄＣｌ２－Ｃｏ（Ｐｙｃａ）２催化剂时，ＤＰＣ的产率为６．０３％。最佳的反应温度是１２０℃，ＤＰＣ的产率随着体系的总压增加而增大，当压力升到３．５ＭＰａ时，ＤＰＣ产率为８．５３％。

| Abstract: | The oxidative carbonylation of phenol to diphenyl carbonate catalyzed by a new Pd - Co catalyst system was studied. When the reaction is carried out at n(PdCl2):n Co( Ⅱ )] :n(TBAB):n(BQ) = 1:1:10:25, T = 120℃, P = 2.5MPa( PCo/Po2 = 4:1 ), reaction time = 8h, PdCl2 - Co(Pyca)2 has higher activity than PdCl2 -Co(OAc)2. The DPC yield is 6.03% for the PdCl2 -Co(Pyca)2 catalyst. The best temperature is 120℃ . The DPC yield is increased with the increase of total pressure. When the pressure reaches to 3.5MPa, the DPC yield is 8.52%. |
