The Synthesis of 5-Hydroxymethylfurfural from Glucose in Biphasic System by Phosphotungstic Acidified Titanium?Zirconium Dioxide

Phosphotungstic acidified titanium?zirconium dioxide catalysts with different loading of phosphotungstic acid (HPA) were synthesized by a precipitation-impregnation method. The phosphotungstic acidified solid acids were characterized by fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD), ammonia temperature programmed desorption (NH3-TPD), X-ray photoelectron spectroscopy (XPS) and transmission electron microscope (TEM) techniques. And the catalytic performance of HPA/TiO2?ZrO2 was explored for glucose degradation to 5-hydroxymethylfurfural (5-HMF) in biphasic system, such as the loading of HPA, the molar ratio of TiO2 to ZrO2, reaction time, temperature, amount of catalyst, the volume ratio of VNaCl(aq)/VTHF and magnetic stirring speed. It was found that activity of the catalyst was related to the amount and density of acid site. The optimized yield of 51.3% for 5-HMF and the optimum conversion rate of 95.4% for glucose were achieved by 5% HPA/TiO2?ZrO2. Meanwhile, recycling performance of the catalyst was investigated. And the catalyst had good thermal stability, the yield of 5-HMF was 41.2% and the conversion rate of glucose remained at 85.4% after five cycles.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C6H12O3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2144-40-3, in my other articles.

Assessment of the antitumor activity of a cyclopalladated ferrocene compound assisted by a dual-targeting drug delivery system

One cyclopalladated ferrocene compound CP was synthesized, which showed a good cell cytotoxicity. Assisted by a dual-targeting drug delivery system, the anticancer activity of CP to MDA-MB-468 remained unchanged, but the toxicity to non-tumorigenic cell line NIH3T3 was remarkably reduced. This provided a new path for the development of cyclopalladated ferrocene as an antitumor drug candidate.

Tuning the chiral cavity of macrocyclic receptor for chiral recognition and discrimination

(Chemical Equation Presented) The size and shape of the chiral cavity of a macrocyclic receptor were tuned by the alteration of the binaphthyl moiety to improve the chiral recognition/discrimination ability. For example, host 3 with the 3,5-bis(trifluoromethyl)phenyl group at the 3,3?-positions showed improved enantioselectivity for small molecules such as 2-chloropropionic acid and methyl lactate as evaluated by the binding constants. This host 3 also had an excellent ability as an NMR chiral solvating agent.

Irradiated ground beef patties: Dose and dose-age estimation by volatile compounds measurement

Volatile compounds produced by irradiation in ground beef patties, packaged under vacuum, were extracted by head-space solid-phase micro-extraction and quantified by gas-chromatography coupled to mass-spectrometry. The study was carried out at levels of irradiation, ranging from 0.5 to 8kGy. Among the 101 detected volatiles compounds, 25 resulted correlated with dose. On the basis of further measurements at 30 and 120 days after irradiation, the most stable compounds with time were identified. To estimate the dose just after irradiation, linear combinations of selections of possible dose markers were obtained via partial least squares regression. A further data analysis showed that it is possible to reconstruct both the irradiation dose and the time elapsed after irradiation from the ratio between the peak areas of some dose markers. The adopted experimental procedure combined with a proper data analysis may lead to dose or dose/age reconstruction in a rapid, simple and efficient way.
