Recycling of high temperature steam condensed water from petroleum refinery by thermostable PPESK ultrafiltration membrane

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.

Heteropolyacid-based ionic liquid [Simp](3)PW12O40 nanoparticle as a productive catalyst for the one-pot synthesis of 2H-indazolo[2,1-b]phthalazine-triones under solvent-free conditions

A novel Keggin-type heteropolyacid-based ionic liquid [Simp](3)PW12O40 was developed via the reaction of the as synthesized ionic liquid 3-sulfonic acid 1-imidazolopyridinium hydrogen sulfate [Simp]HSO4 with an aqueous solution of H3PW12O40. Then, the formulated [Simp](3)PW12O40 was changed to the nano-form via solvothermal processing in tetralin at 220 degrees C. After that, the provided powdered solid nanomaterial was characterized by FTIR, H-1 NMR, XRD, SEM, EDX and TGA analyses. Then, the focused nanomaterial was handled as a productive and encouraging nanocatalyst for the establishment of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione attendants through one-pot, multi-component contraction of aldehydes, phthalhydrazide, and dimedone under solventless status and the generality and practical tolerance of this useful and environmentally benign method are illustrated. The simple work-up, smooth reaction conditions, good to excellent yields, and reasonably short reaction times are the particular benefits of this protocol. Besides, the new nano-powdered ionic liquid was a successful and modest catalyst that could definitely be recycled and reused several times without apparent decrease in its catalytic activity.

Synthesis and In vitro Analysis of Novel Dihydroxyacetophenone Derivatives with Antimicrobial and Antitumor Activities

Herein we report a feasible study concerning the design, syntheses and in vitro antimicrobial and antitumoral activities of some novel compounds with dihydroxyacetophenone (DA) moiety. An efficient and general method for the preparation of diazine with dihydroxyacetophenone (DDA) skeleton under conventional thermal heating (TH), microwave (MW) and ultrasounds (US) irradiation is presented. Antimicrobial and antitumoral tests prove that some dihydroxyacetophenone compounds (the brominated derivatives BrDA 3) have a significant biological activity. It is also to be pointed out that, basically all the dihydroxyacetophenone derivatives proved to have a powerful antibacterial activity against drug resistant Gram-negative strain Pseudomonas aeruginosa ATCC 27853. Of particular interest could be the excellent antibacterial activity of our dihydroxyacetophenone compounds against drug resistant Gram-negative strain Pseudomonas aeruginosa.

Aromatic azaheterocycle-cored luminogens with tunable physical properties via nitrogen atoms for sensing strong acids

A series of luminogens comprising one pyridine, 1,3-diazine, 1,4-diazine, 1,2-diazine and phthalazine moiety as the central core and two AIE-active tetraphenylethene units in lateral positions have been readily synthesized by Suzuki cross-coupling. They exhibited remarkably different photophysical and electrochemical properties, as well as solid packing and fine controllability via the number and position of the nitrogen atoms in the aromatic azaheterocycle core. Among them, the pyridine, 1,3-diazine and 1,4-diazine-cored luminogens displayed strong AIE activities, whereas the 1,2-diazine and phthalazine-cored luminogens exhibited almost no AIE effect. The intrinsic Lewis basicity of the as-prepared luminogens endowed them with the ability to fluorometrically detect acids with different pK(a) values. When protonated by a strong acid such as trifluoroacetic acid, the pyridine, 1,3-diazine and 1,4-diazine-cored luminogens displayed relatively weak AIE effects. In contrast, the 1,2-diazine and phthalazine-cored luminogens exhibited highly sensitive responses to strong acids within a precise pKa range by displaying turn-on fluorescence emissions in the low-energy region, which was probably owing to the synergetic effect of AIE and the constraint of the intersystem crossing effect upon protonation of the 1,2-diazine segment. They displayed reversible acidochromism in response to protonation and deprotonation in the solid state. Such unique properties of the as-prepared luminogens could be used for the selective discrimination of some organic acids, which is highly valuable in the study of biological metabolism.

Mononuclear ruthenium compounds bearing N-donor and N-heterocyclic carbene ligands: structure and oxidative catalysis

A new CNNC carbene-phthalazine tetradentate ligand has been synthesised, which in the reaction with [Ru(T)Cl-3] (T = trpy, tpm, bpea; trpy = 2,2′; 6′, 2”’-terpyridine; tpm = tris(pyrazol-1-yl)methane; bpea = N, N-bis(pyridin-2-ylmethyl) ethanamine) in MeOH or iPrOH undergoes a C-N bond scission due to the nucleophilic attack of a solvent molecule, with the subsequent formation of the mononuclear complexes cis-[Ru(PhthaPz-OR)(trpy) X](n+), [Ru(PhthaPz-OMe)(tpm) X](n+) and trans, fac-[Ru(PhthaPz-OMe) (bpea) X] n+ (X = Cl, n = 1; X = H2O, n = 2; PhthaPz-OR = 1-(4-alkoxyphthalazin-1-yl)-3-methyl-1H-imidazol- 3-ium), named 1a(+)/2a(2+) (R = Me), 1b(+)/2b(2+) (R = iPr), 3(+)/4(2+) and 5(+)/6(2+), respectively. Interestingly, regulation of the stability regions of different Ru oxidation states is obtained by different ligand combinations, going from 6(2+), where Ru(III) is clearly stable and mono-electronic transfers are favoured, to 2a(2+)/2b(2+), where Ru(III) is almost unstable with regard to its disproportionation. The catalytic performance of the Ru-OH2 complexes in chemical water oxidation at pH 1.0 points to poor stability (ligand oxidation), with subsequent evolution of CO2 together with O-2, especially for 4(2+) and 6(2+). In electrochemically driven water oxidation, the highest TOF values are obtained for 2a(2+) at pH 1.0. In alkene epoxidation, complexes favouring bi-electronic transfer processes show better performances and selectivities than those favouring mono-electronic transfers, while alkenes containing electron-donor groups show better performances than those bearing electron-withdrawing groups. Finally, when cis-beta-methylstyrene is employed as the substrate, no cis/trans isomerization takes place, thus indicating the existence of a stereospecific process.
