Cynoglossum amabile Stapf et Drumm is widely distributed in southern China, which has been used as an anti-inflammatory, antihepatitis, anticystitis agent in Chinese folk medicine[1]. However, only a few phytochemical researches have been performed[2]. 相似文献

Three crystal architectures, including one organic compound of benzoyl peroxide(1) and two clusters of tri-iron(Ⅲ) and bi-cupper(Ⅱ) with benzoic ligands(2 and 3), were self-assembled by an in situ redox way of benzoyl peroxide oxidants reacting with Mo, Fe and Cu powders, respectively. X-ray crystallographic results show that both the asymmetry tri-iron(Ⅲ) cluster and the benzoylperoxide crystal architecture(2 and 1) with complicated 3D networks were constructed by intermolecular hydrogen-bonding interactio... 相似文献

Oxidative dehydrogenation of propane to propene was investigated over Ba- promoted Ni0.9MoO4 catalysts (molar ratio of Ba/Mo: 1%, 3%, 6%, 9%, 12%, 15%). The selectivity for propene increases with the increasing number
of basic sites on the catalyst, and molybdenum ions play an important role in propane activation. No significant deactivation
of the 6% Ba- Ni0.9MoO4 and Ni0.9MoO4 at 773 K for 80 h and for 40 h, respectively, appeared, indicating that the 6% Ba- Ni0.9MoO4 has great advantage over the Ni0.9MoO4.
