Now introduce a scientific discovery about this category.

The purification and reclaiming of synthetic and industrial high temperature condensed water containing excess oil and iron is investigated in this study using thermostable poly(phthalazine ether sulfone ketone) (PPESK) ultrafiltration membranes. The results show operation parameters such as transmembrane pressure, temperature and pH of feed solution, initial oil and iron concentration each play important roles in the permeate flux and oil/iron removal efficiencies. Membrane performance is almost recovered after washing with a combination of NaOH and ethanol. High temperature condensed water from Daqing petroleum refinery can be consecutively purified using a PPESK ultrafiltration membrane. The turbidity of the solutions is almost removed. Oil and iron concentrations in the permeate solutions are below 1 mg/L and 50 mu g/L, respectively, which satisfy the Quality Criterion of Water and Steam for Steam Power Equipment in China. UF process shows a promising alternative to existing technology in the Daqing petroleum refinery in terms of cost and environmental protection as well as energy recovery. For future possible combination of UF and NF process application, both economic cost and saving are evaluated, and the breakeven time is about 11 months. (C) 2013 Elsevier B.V. All rights reserved.

Synthetic Route of 35661-39-3, Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 35661-39-3, Name is Fmoc-Ala-OH, SMILES is C[C@H](NC(OCC1C2=C(C3=C1C=CC=C3)C=CC=C2)=O)C(O)=O, belongs to phthalazine compound. In a article, author is Kiasat, Ali Reza, introduce new discover of the category.

A simple, efficient, and high yielding one-pot protocol for the synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives has been developed by three-component coupling of phthalhydrazide, dimedone and some aromatic aldehydes in ecofriendly neat conditions promoted by nano-gamma-alumina sulforic acid. This protocol avoids the use of expensive catalysts, toxic solvents and chromatographic separation. Also the proposed protocol was extended to the linear beta-diketone (acetylaceton) instead of cyclic diketone (dimedone). The generality and functional tolerance of this convergent and environmentally benign method is demonstrated. The nature of each step of the suggested mechanism for this condensation reaction is also identified through Density Functional Theory (DFT) calculations using B3LYP/6-31G** level of theory. It is shown that the first step is charge controlled; whereas the second one is controlled by frontier molecular orbitals. The H-1 and C-13 chemical shift values together with the structural parameters of the title compound have been also computed and the scaled values have been compared with the corresponding experimental NMR and X-ray spectra. As a result, the calculated spectroscopic data and optimized geometry show a good agreement with the experimental results. (C) 2012 Elsevier B.V. All rights reserved.

New coordination compounds have been synthesized by reacting Zn(II) and Co(II) nitrate or acetate in the presence of triethylamine with Schiff-base ligands containing diazine-ring, pyridine-2-carbaldehyde phthalazine-1-hydrazone,HzPYH, and di(2-pyridyl)ketone 3-chloro-pyridazine-6-hydrazone,HpDPKH. Complexes of[Co(HzPY)(2)]center dot 3.4H(2)O,[Zn(HzPY)(2)]and[Co(HpDPK)(2)]NO3 center dot H(2)Owere obtained. The crystal and the molecular structure of[Co(HzPY)(2)]center dot 3.4H(2)Owere determined using X-ray diffraction structure analysis. The compounds were characterized by elemental analysis, FT-IR and UV-Vis spectral data, conductivity and magnetic measurements, too. Except for the diamagnetic Co(III) compound with a nitrate counter-ion,[Co(HpDPK)(2)]NO3 center dot H2O, all the complexes are neutral-type. The magnetic moment of[Co(HzPY)(2)]center dot 3.4H(2)Oindicated a low-spin octahedral complex which is relatively rear amongst octahedral Co(II) complexes. Hence, its magnetic moment was measured in the temperature range of 3-300 K. To obtain products in the form of single crystals and/or to increase the yield, the reactions were carried out in solutions with different solvents or recrystallized from solvent mixtures. To determine the nature of the solvent (if any) in the crystalline products and to gain better insight into the decomposition mechanism, coupled TG-MS measurements were carried out. The desolvated compounds were stable at relatively high temperatures (> 200 degrees C). The cytotoxic, antiproliferative and efflux pump inhibitory effects of the compounds were tested in multidrug-resistant mouse T-lymphoma cells to study their effect on the suppression of MDR. The antibacterial activity of the compounds was also tested. The results of the antibacterial tests were analysed to understand better the effect of the central atoms and the structure on a specific activity.

The present work describes convenient synthesis of the novel Schiff bases 5a and b by reacting phthalazinones 4a and b with 4-methoxybenzaldehyde Reaction of the Schiff bases with phenylisothiocyanate afforded diazetidine derivatives 7a and b. Also, compounds 4a and b reacted with 2-bromoglucoside tetraacetate giving peracetylated N-glycosides 6a and b, which were deacetylated to afford N-glycosylated phthalazinones 8a and b. On the other hand, when compound 3 was treated with POCl3/PCl5 and/or ethyl chloroacetate, chlorophthalazine and ethyl acetate derivatives 9 and 10 were obtained, respectively. Hydrazinolysis of compounds 9 and 10 produced the hydrazino and hydrazide derivatives 11 and 12, respectively. When compound 11 reacted with 2-furanaldehyde, acetic anhydride, and/or carbon disulphide, it gave compounds 13-15, respectively. Treatment of the hydrazide 12 with aromatic aldehydes, acetic anhydride, ethyl acetoacetate, acetyl acetone, ammonium thiocyanate, and/or phthalic anhydride furnished compounds 17-21. Meanwhile, reacting Schiff base 22 with the chlorophthalazine derivative 9 produced compound 23, which on treatment with furoyl chloride produced compound 24. The structures of the novel compounds were confirmed by IR, H-1-NMR, C-13-NMR, MS, and elemental analysis. The newly synthesized compounds were tested against Bacillus subtilis and Staphylococcus aureus as Gram-positive bacteria, Escherichia coli and Pseudomonas aurignosa as Gram-negative bacteria, and Candida albicans and Aspergillus niger as fungi strains. Compounds 5a and b, 23, and 24 showed greater antimicrobial activity than the stranded compounds, suggesting that they could be considered as promising antimicrobial agents.

Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , SDS of cas: 587-04-2, 587-04-2, Name is 3-Chlorobenzaldehyde, molecular formula is C7H5ClO, belongs to phthalazine compound. In a document, author is Yu, Li-Jun, introduce the new discover.

In a previous research, we found a compound named 6-(3-(trifluoromethyl)-benzyloxy)-[1,2,4]triazolo[3,4-a]phthalazine (BM-1) much more effective in the maximal electroshock (MES) model for mouse and much safer in the neurotoxicity (NT) screening, which indicated that it may be used as antiepileptic drug. But, those evaluations were too rough. So in this study, we did more work to assess the anticonvulsant activity and the toxicity about BM-1. The peak times of protection of BM-1 after intraperitoneal injection (ip) and oral administration (po) were determined using the MES test, and the anticonvulsant activity of it was compared with the reference drug, carbamazepine, at these peak times. The rotarod test was applied to measure its neurotoxicity. When compared with the reference drug in the maximal electroshock (MES) test at the time to peak effect, it showed that BM-1 was much more effective and safer than reference drug Carbamazepine with ED50 of 11.2 mg/kg, TD50 of 72.2 mg/kg and PI of 6.5 after administration of ip, while when administered orally, that values of ED50, TD50 and PI of BM-1-1, BM-1-2 and BM-1-3 were much better than Carbamazepine and BM-1 after po. The compound BM-1 has more effective anticonvulsant activity and lower neurotoxicity administered by both ip and po. So BM-1 could may be used instead of the prescribed antiepileptic drugs (AEDs) in the future.
