  Structure effect of activated carbon in Ru/AC catalysts for hydrogenation of phthalates

  摘要：

  Activated carbon with different microporous surface area were used to prepare a series of Ru/AC catalysts for the hydrogenation of dioctyl phthalate (DOP) to dioctyl 1,2-cyclohexanedicarboxylate (DOCH). The presence of micropores benefit the dispersion of Ru, but Ru particles encapsulated into the micropores can be hardly accessed by DOP molecule. An appropriate microporous surface area of the support should be crucial important for the preparation of highly efficient catalyst for phthalates hydrogenation. The as-prepared 0.45%Ru/AC-2 catalyst (Micropore surface area = 604 m(2)/g) exhibited the best activity in DOP hydrogenation with a TOF of 1406 h(-1) due to its suitable micropore surface area.

  effective hydrogenation catalyst, yielding >99% ring-hydrogenated products under mild reaction conditions (0.1 mol% Ru, 80 °C, 50 bar H2). However, applying this reaction to PVC-extracted phthalates proved problematic, (1) as benzyl phthalates are hydrogenolyzed to benzoic acids that inhibit the Ru-catalyst, and (2) because impurities in the plasticizer extract (PVC, sulfur) further retard the hydrogenation

  回收报废聚氯乙烯 (PVC) 需要解决方案来处理历来掺入 PVC 中的大量有害邻苯二甲酸酯增塑剂。在这里，我们报告了通过催化一锅（转）酯化 - 加氢过程将这种从废物中提取的邻苯二甲酸酯升级为更安全的 1,2-环己烷二羧酸二异壬酯增塑剂（DINCH）的类似物。对于大多数原生邻苯二甲酸盐，Ru/Al 2 O 3是一种高效的氢化催化剂，在温和的反应条件下（0.1 mol% Ru，80 °C，50 bar H 2）。然而，将该反应应用于 PVC 提取的邻苯二甲酸酯被证明存在问题，(1) 因为邻苯二甲酸苄酯被氢解为抑制 Ru 催化剂的苯甲酸，以及 (2) 因为增塑剂提取物中的杂质（PVC、硫）进一步阻碍了氢化. 这些复杂的问题通过将氢化与高级醇的原位（转）酯化相结合，并用活性炭吸附剂预处理提取物来解决。通过这种方式，从消费后的 PVC 废料中获得的真正邻苯二甲酸酯提取物最终完全 (>99%) 氢化为不含邻苯二甲酸酯的脂环族增塑剂。
