A water-soluble β-cyclodextrin polymer synthesized by crosslinking β-cyclodextrin with epichlorohydrin and glycidyltrimethylammonium chloride allowed the stabilization of ruthenium nanoparticles not only in basic aqueous medium but also in acidic medium. The aqueous ruthenium colloidal suspensions obtained with this polymer were active as catalysts for the hydrogenation of a large variety of unsaturated compounds including aromatic or fatty acids. The recycling of this catalytic system was attested through ten consecutive runs without loss of stability and activity, demonstrating its robustness.

耐酸环糊精基钌纳米颗粒用于水中不饱和化合物的氢化

通过将β-环糊精与表氯醇和缩水甘油基三甲基氯化铵交联而合成的水溶性β-环糊精聚合物不仅使钌纳米颗粒在碱性水性介质中而且在酸性介质中均稳定。用该聚合物获得的钌胶体水悬浮液具有催化氢化包括芳族或脂肪酸在内的各种不饱和化合物的活性。经过十次连续运行证明了该催化体系的循环利用，而没有失去稳定性和活性，证明了其坚固性。
