The traditional manufacturing process of 1,3-dioxolane requires high investment and energy consumption. A reactive distillation with pressure-swing distillation process is proposed as an attractive candidate based on the process simulation results in this work. To simulate the reactive distillation process, the kinetics experiments of formaldehyde aldolization with ethylene glycol were performed over NKC-9 cationic-exchange resin catalyst at 353-368 K. Byproducts were observed, and the batch distillation experiment were carried out to determine the boiling point temperatures ranking. A calculation strategy of aqueous and ethanediolic formaldehyde solutions was developed to solve the vapor-liquid equilibrium. The sensitivity analysis result shows that the yield of 1,3-dioxolane could be improved to 0.995 in the reactive distillation column, and high-purity 1,3-dioxolane (99.9 wt %) can be obtained in the following pressure-swing distillation process. The research achievements provides a new 1,3-dioxolane production process, which has an advantage in equipment integration.

3-Nitroindenoisoquinoline human topoisomerase IB (Top1) poisons have potent antiproliferative effects on cancer cells. The undesirable nitro toxicophore could hypothetically be replaced by other functional groups that would retain the desired biological activities and minimize potential safety risks. Eleven series of indenoisoquinolines bearing 3-nitro bioisosteres were synthesized. The molecules were evaluated in the Top1-mediated DNA cleavage assay and in the National Cancer Institute’s 60 cell line cytotoxicity assay. The data reveal that fluorine and chlorine may substitute for the 3-nitro group with minimal loss of Top1 poisoning activity. The new information gained from these efforts can be used to design novel indenoisoquinolines with improved safety.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Application of 496-41-3, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 496-41-3, molcular formula is C9H6O3, introducing its new discovery.

The coumarilate (coum?) and 1,10-phenanthroline (phen) mixed ligand complexes of Co(II) (1), Ni(II) (2) Cu(II) (3) and Zn(II) (4) were synthesized and structural characterizations were performed by using elemental analysis, magnetic susceptibility, solid-state UV?Vis, FTIR spectra, thermoanalytical TG-DTG/DTA and single-crystal X-ray diffraction methods. The Co(II) and Ni(II) complexes are salt-type compounds, and they have two moles phen ligands bound as bidentate, two moles aqua ligands in coordination sphere and two moles anionic coum? ligand outside of the coordination unit as the counter-ion of the molecular structure. At the same time, the Co(II) and Ni(II) complexes have five moles of aqua ligands as hydrated water outside of the molecules. It was obtained that Cu(II) and Zn(II) complex structures contain one mole of phen ligand, two moles coordinated (coum?) ligand and a one-mole aqua ligand, and the molecules (Cu(II) and Zn(II)) have fivefold structure and obey square pyramidal geometry. Thermal decomposition of each complex started with dehydration (the first removal is the dehydration of complex Co(II) and Ni(II) as removal of hydrate?aqua molecules), and then, the decomposition of organic parts was observed. The thermal dehydration of the complexes takes place in one (Cu(II) and Zn(II)) or two (Co(II) and Co(II)) steps. The decomposition mechanism, thermal decomposition steps and thermal stability of the investigated complexes provide useful data for the interpretation of their structures. The final decomposition products were found to be metal oxides. Some biological applications (antifungal/antibacterial) were performed using structurally characterized compounds.

This paper presents the prediction of remaining service life of the land concrete as distinguished from the marine concrete. This study assumes that the land concrete is deteriorated by following three cases: carbonation, using sea sand and using deicing salts. In case of carbonation deterioration, statistical analysis and the depth of carbonation front are considered. This depth is assessed about 3.6-8.3 mm and can give more exact prediction than just carbonation depth by phenolphthalein. In case of using sea sand, various specimens considering chloride contents, carbonation accelerating, cover depth, relative humidity and water cement ratio are measured by linear polarization resistance method and half-cell potential method during the 1 year. And measurements of the real steel loss give the conversion ratio of polarization resistance and corrosion rate; consequently, their results make the prediction equation of rust growth during any specified period. In case of using deicing salts, surface chloride contents that change with time are focused. The proposed methods are considered to be useful for prediction of remaining service life of the land concrete by steel corrosion.

Three illustrative examples are presented from our own approaches to development of drug candidates based on structure-activity relationship analyses. Starting from a lead, 3-(S)-n-butyl-phthalide, an anticonvulsive principle, isolated from Chinese celery seeds, a number of congeners were synthesized and tested. Quantitative structure-activity relationship (QSAR) analyses revealed that the potency depends upon the configuration of substituents around the chiral center at the 3-position, in addition to the hydrophobicity and electronic structure of compounds, and the polarity of substituents in the aromatic moiety. RS-3-n-Butyl-6-amino-phthalide was selected as a candidate for antiepileptic drug. A series of modifications of an antipeptic-ulcer prototype, furazolidone, led to deduction of a lead skeleton. A series of related (hetero) aromatic aldehyde (thio) semicarbazones were synthesized and tested. The QSAR analyses showed that the activity is significantly dependent on the electron density of the (thio) carbonyl group, which is enhanced by the introduction of electrons-donating substituents. Hepatoprotective biphenyl compounds with structures simplified from that of an active principle of a Chinese traditional medicine, were investigated by the analysis of structural parameters obtained from their X-ray crystallography and UV spectrum. The structural requirements for activity were suggested from their configuration and conformation.
