The solubility and the critical relative humidity (H(cr)) of 14 drugs and inorganic salts were determined, the relationship between the H(cr) and the solubility was explored theoretically, and the H(cr) was calculated in the light of Raoult's law and Pitzer ion interaction model from their solubility. The results indicate that the H(cr) values calculated by Raoult's law in high humidity (H(cr)>80%) and by Pitzer ion interaction model in low humidity (H(cr)<80%) are comparable to the measured ones. 相似文献

A mild, simple process for the effective deoximation of a wide range of ketoximes and aldoximes has been developed, which utilizes available NaNO(2) as the catalyst and molecular oxygen as the green oxidant. Notably Amberlyst-15, which acts as the initiator of NaNO(2), can be reused without regeneration. This environmentally benign protocol could provide a valuable synthetic method for practical applications. 相似文献

A facile, practical and scalable catalyst system for alcohols ammoxidation into nitriles was developed using amino acid as ligand, oxygen as terminal oxidant and copper iodide(CuI) as catalyst. The catalyst system shows excellent functional groups compatibility for a wide range of testing substrates, even the substrates bearing oxidation- sensitive groups such as MeS-, alkenyl and -NH2 can also work well. In addition, the protocol is readily scaled up to more than 20 g and the product can be obtained just through filtration or distillation without conventional column chromatography. 相似文献

In this paper, we investigate the problem of synchronization for the time varying delayed complex dynamical networks via impulsive control method, several sufficient synchronization conditions are given, and we consider the impulsive control matrices are time varying delayed matrices. Furthermore, we found impulsive control does not always play an active role in synchronization although impulsive control strategy is cheaper and simpler than other control strategy. Finally, numerical simulations are also given to demonstrate the effectiveness of the proposed schemes. 相似文献

NiO nanosheets with uniformly distributed mesoporosity were successfully synthesized on a large scale by calcination of β-Ni(OH)2 nanosheet precursor, which was simply prepared using 1,6-hexanediamine-assisted solution approach. The as-prepared mesoporous NiO nanosheets have been introduced for the first time for the sensing of mercury ions, which were found to be useful for selective electrochemical detection of Hg2+ with a linear range of 0.8 to 500?μM in pH?6.0 phosphate-buffered solutions, providing us another opportunity for exploring new electrochemical application of NiO nanomaterials. 相似文献
