--This research is aimed to investigate experimentally the performance and exhaust emission characteristics of a direct injection (DI) diesel engine when fuelled with blends of conventional diesel fuel and ethanol, blends of rice bran methyl ester with ethanol, blends of diesel and rice bran methyl ester over the entire range of load on the engine. The experimental results showed that the highe...

The title compound, [Cu2I2(C11H22N2)2], crystallizes as a symmetric dimer with one quarter of the mol-ecule in the asymmetric unit. The copper(I) atom, the iodine atom and the central methyl-ene C atom of the di(piperidin-1-yl)methane ligand lie on a mirror plane and the complete molecule exhibits point group symmetry 2/m. To the best of our knowledge it is the first di-amine copper(I) complex ...

In this study, research will be carried out to identify the functional group behavior of glassy and rubbery polymeric blend membrane with amines. Polymeric blend membranes with different blending ratios were prepared and the developed membranes were characterized by FTIR to see the effect of blend ratio on different functional groups. The developed membranes are flat dense sheet membrane of 20%...

The mononuclear nickel title complex (acetonitrile-κN){N-benzyl-N,N',N'-tris-[(6-methyl-pyridin-2-yl)meth-yl]ethane-1,2-di-amine}-nickel(II) bis-(tetra-fluor-ido-borate), [Ni(C30H35N5)(CH3CN)](BF4)2, was prepared from the reaction of Ni(BF4)2·6H2O with N-benzyl-N,N',N'-tris-[(6-methyl-pyridin-2-yl)meth-yl]ethane-1,2-di-amine (bztmpen) in aceto-nitrile at room temperature. With an open site occu...

The title compound, C20H18N4, was obtained via the condensation of 4,5-di-methyl-benzene-1,2-di-amine with pyridine-2-carbaldehyde. The plane of the 2-(pyridin-2-yl) substitutent is canted by 2.75 (11)° from the plane of the benzimidazole system. The mol-ecule exhibits an S(6) C-H⋯N intra-molecular hydrogen-bond motif. In the crystal, C-H⋯N hydrogen bonds link pairs of mol-ecules related by a c...

The reaction of CuSO4·5H2O, 4-chloro-pyrazole (4-Cl-pzH) and tri-ethyl-amine (Et3N) in di-methyl-formamide (DMF) produced crystals of di-aqua-hexa-kis-(μ-4-chloro-pyrazolato-κ(2) N:N')bis-(N,N-di-methyl-formamide)di-μ3-hydroxido-bis-(μ4-sulfato-κ(4) O:O':O'':O'')hexa-copper(II) N,N-di-methyl-formamide tetra-solvate dihydrate, [Cu3(OH)(SO4)(C3H2ClN2)3(C3H7NO)(H2O)]2·4C3H7NO·2H2O. The centrosymme...

The title salt, C12H10BrN3O(2+)·2Br(-), was synthesized from the reaction of N (1),N (4)-bis-(pyridin-2-yl-methyl-idene)benzene-1,4-di-amine and bromine in a methanol solution. All non-H atoms of the 2-aza-niumyl-3-bromo-6-oxo-5,6-di-hydro-pyrido[1,2-a]quinoxalin-11-ium cation are nearly coplanar, the maximum deviation being 0.114 (4) Å. In the crystal, the cations and anions are linked through...

The title compound, C(42)H(72)N(2)O(5), a hindered amine light stabiliser (HALS) with the trade name Tinuvin 144 was prepared from bis-(1,2,2,6,6-penta-methyl-piperidin-4-yl) 2-butyl-malonate and 2,6-di-tert-butyl-4-[(dimethyl-amino)meth-yl]phenol using lithium amide as a catalyst. In the mol-ecule, both piperidine rings adopt chair conformations. In the crystal, inversion dimers linked by pair...

Zirconium amides have become increasingly popular and useful due to their widespread use as precursors to other zirconium complexes and their use in the production of solid oxide fuel cells (SOFCs). Herein we report the mol-ecular structure of tris-(di-methyl-amido)-bis-(di-methyl-amine)-zirconium(IV) iodide, [Zr(C2H6N)3(C2H7N)2]I. The bond lengths and bond angles are consistent with a slightly...

The non-symmetric title mol-ecule, C32H34N2O5, is based on a tetra-substituted ethyl-enedi-amine backbone. The mol-ecular structure consists of three hy-droxy-benzyl groups and one 2-hy-droxy-5-methyl-benzaldehyde group bonded to the N atoms of the di-amine unit. The ethyl-enedi-amine skeleton shows a regular extended conformation, while the spatial orientation of the phenol arms is governed by...
