  水中坚固的固体 NHC-Rh 配位组件催化苯酚选择性加氢生成环己醇

  摘要：

  由于其固有的不稳定性，开发用于苯酚加氢的可行的过渡金属催化剂具有挑战性，这阻碍了真正催化活性物质的识别及其可重复使用性。为了克服这个问题，我们采用了自支撑策略来防止催化剂团聚。这种方法导致 NHC-Rh 配位组件的形成，该组件可作为稳健且选择性的固体分子催化剂，用于在温和条件下将水中的苯酚氢化为环己醇。值得注意的是，这些固体催化剂表现出卓越的稳定性，最多可连续重复使用 9 次，而不会影响其活性或选择性。这一进步为未来工业中有价值的环己醇的生产提供了一种有前途且可持续的解决方案。

  Principal solvents, especially mono-ol and diol principal solvents, having a ClogP of from about 0.15 to about 0.64, preferably from about 0.25 to about 0.62, and more preferably from about 0.40 to about 0.60, are disclosed that have the ability to make clear aqueous fabric softener compositions containing relatively high concentrations of fabric softener actives having ester linkages in their long, hydrophobic chains. The fabric softener actives are either unsaturated, or have intermediate length chains (˜C 12-14 ) and the said principal solvents are used at levels of less than about 40%. Other solvents may be present. Some of the said principal solvents are novel compounds and/or novel mixtures. Premixes of the fabric softening actives, the principal solvents, and, optionally, other solvents are useful in the preparation of complete formulations by obviating/limiting the need for heating.
