In the title compound, C(14)H(9)Cl(2)N(3)O(3)S·C(3)H(7)NO, the two aromatic rings enclose a dihedral angle of 32.93 (12)°. The thiourea mol-ecule exists in its thione form in the solid state with typical C=S and C-N bond lengths. In the crystal, N-H⋯O hydrogen bonds exist between the thio-urea and carbonyl groups on the same and neighboring mol-ecules. In addition, each dimethyl-formamide solva...

In the title compound, [Ni(C(19)H(13)N(5))(2)](C(6)H(2)N(3)O(7))(2)·2C(3)H(7)NO, the Ni(II) ion is coordinated by two tridentate 2,6-bis-(1H-benzimidazol-2-yl)pyridine ligands in a distorted octa-hedral geometry. In the crystal structure, the picrate anions and solvent dimethyl-formamide (DMF) mol-ecules are connected to the cation via inter-molecular N-H⋯O hydrogen bonds. Further stabilization...

Wood shortages, environmental pollution and high energy consumption remain major obstacles hindering the development of today's pulp and paper industry. Energy-saving and environmental friendly pulping processes are still needed, especially for non-woody materials. In this study, soda-oxygen pulping of bagasse was investigated and a successful soda-oxygen pulping process for bagasse at 100 °C w...

Comparative study on organosolv pulping method have been done by using various mixtures of water and organic solvents as delignifying agents including ethylene glycol-water mixtures, ethanol-water mixtures and acetic acid-water mixtures to extract cellulose from agricultural crop biomass (Oil palm empty-fruit bunches-OPFB). The yield of organosolv pulping with ethylene glycol-water mixture, eth...

soda and soda-aq pulping of corn stalk applying different charges of active alkali and pulping time was studied. the average value of fiber length, diameter and cell wall thickness were measured as 1.03 mm, 23.64 µm and 5.26 µm, respectively. the content of alcohol-acetone extractives, cellulose, lignin, extractives soluble in 1% naoh and ash content of corn stalk were determined as 15%, 51.2%,...

Three novel bismuth(III) complexes with in situ synthesized dihydroxybenzoquinone (anilic acid) ligands, namely [Bi(H(3)dhbqdc)(H(2)dhbqdc)]·2.5dmf (1), [Bi(2)(mdhbqdc)(ox)(2)(dmf)(4)] (2) and [Bi(2)(mdhbqdc)(2)(ox)(dmf)(4)] (3) (H(4)dhbqdc = 3,6-dihydroxy-2,5-benzoquinone-1,4-dicarboxylic acid; H(2)mdhbqdc = dimethyl 3,6-dihydroxy-2,5-benzoquinone-1,4-dicarboxylate, ox = oxalate, dmf = dimethy...

Copper oxide nanostructures have been successfully synthesized via one-step solid-state thermolysis of two metal-organic frameworks, [Cu3(btc)2] (1) and [Cu(tpa).(dmf)] (2), (btc = benzene-1,3,5-tricarboxylate, tpa = therephtalic acid = 1,4-benzendicarboxylic acid and dmf = dimethyl formamide) under air atmosphere at 400,  500, and 600°C. It has also been found that the reaction temperature pla...

The reaction of cobalt(II) acetate with 2-iodoterephthalic acid and 1,10-phenanthroline (phen) in N,N-dimethylformamide (DMF) leads to formation two products, hexakis(N,N-dimethyl-formamide-κO)cobalt(II) bis(iodide) (1) MOF [Co(TP)(phen)·2DMF·2H2O] (2), where TP is terephthalate dianion. Compound 1 crystallizes the monoclinic space group Р2 1/с cell parameters a = 14.2974(4) Å, b 10.7983(4) c 2...
