腰果酚是一种绿色的可再生生物质基酚类化合物，从制备高耐候性、高耐腐性的生物基树脂和涂料的角度，控制长侧链碳碳双键的数量非常关键，因为较多数量的不饱和双键容易发生自缩聚反应，而且它们也会影响酚羟基的稳定性。另一方面，全饱和侧链的腰果酚稳定性高，但作为树脂组分交联偶合性降低。本发明的镍基合金催化剂，应用于腰果酚加氢反应，既可在温和条件下侧链全加氢，也可获得超过50%单烯组分腰果酚(同时基本转化二烯/三烯组分)。表现出与常规雷尼镍催化剂显著不同的特点，从而能够较大余度地调控腰果酚的反应性、稳定性与交联性，对制备高性能生物基涂料具有重要意义。

Cashew phenol is a green renewable biomass based phenolic compound. From the perspective of preparing high weather and corrosion resistant bio based resins and coatings, controlling the number of long side chain carbon carbon double bonds is crucial because a large number of unsaturated double bonds are prone to self condensation reactions, and they also affect the stability of phenolic hydroxyl groups. On the other hand, cashew phenols with fully saturated side chains have high stability, but their crosslinking coupling as resin components decreases. The nickel based alloy catalyst of the present invention can be applied to the hydrogenation reaction of cardanol, which can not only fully hydrogenate the side chain under mild conditions, but also obtain more than 50% of the monoene component cardanol (while basically converting the diene/diene component). It exhibits significantly different characteristics from conventional Raney nickel catalysts, which can regulate the reactivity, stability, and cross-linking of cashew phenol with a large margin, and is of great significance for the preparation of high-performance bio based coatings.
