The blackbody infrared radiation induced dissociation of methyl benzoate (C8H8O2(+*)) radical cation was investigated by using a Fourier transfer ion cyclotron resonance mass spectrometer equipped with a resistively heated (wire temperatures of 400-1070 K) wire ion guide. We observed product ion branching ratios that are strongly dependent upon wire temperature. At low temperatures (670-890 K) ...

To determine the non-bonded interaction between methyl benzoate and boron nitridenanotube, we focused on an armchair single-wall boron nitride nanotube (9,9) With length 5 angstroms.The geometry of molecules was optimized using B3LYP method with 6-31g* basis set. Also reactivityand stability of methyl benzoate and boron nitride nanotube (9,9) was checked. Then NBO, FREQ,...

The work in this report describes the syntheses, characterization, crystal structures and magnetic properties of eight linear trinickel(ii) compounds of the composition [Ni(II)3(L(sal-pyr))2(propionate)4] (), [Ni(II)3(L(sal-pyr))2(benzoate)4]·CH3CN (), [Ni(II)3(L(sal-pip))2(acetate)4]·2CH3CN (), [Ni(II)3(L(sal-pip))2(propionate)4] (), [Ni(II)3(L(sal-pip))2(benzoate)4]·CH2Cl2 (), [Ni(II)3(L(sal-...

Ebastine, 4-(benzhydr-yloxy)-1-[4-(4-tert-butyl-phen-yl)-4-oxobut-yl]piperidine, reacts with 3,5-di-nitro-benzoic acid in methanol solution to give the title 1:1 salt, ebastinium 3,5-di-nitro-benzoate, C32H40NO2+·C7H3N2O6-. In the cation, the disubstituted aryl ring exhibits orientational disorder over two sets of atomic sites having occupancies 0.706 (4) and 0.294 (6), with a dihedral angle of...

background: anecdotal information has suggested that sodium benzoate is used with more than permissible doses during production steps of food products especially pickles and pickled cucumbers in food producing factories in markazi province and other food producing factories . the present study was done to evaluate factual concentration of sodium benzoate in these products. methods: in this stud...

The principle of isotachophoresis has been used to develop a simple, specific and sensitive analytical method for the determination of anions in untreated urine. Isotachophoretic separation of anions in the presence of complex-forming counter ions (e.g. Cd2+) enables the quantitative separation and determination of chloride, sulphate and orthophosphate in the same sample and the less accurate m...

The title compound, [Ni(2)(C(7)H(5)O(2))(4)(C(7)H(6)O(2))(2)], is composed of two Ni(II) ions, four bridging benzoate anions and two η(1)-benzoic acid mol-ecules. The [Ni(2)(PhCOO)(4)] unit adopts a typical paddle-wheel conformation. The center between the two Ni(II) atoms represents a crystallographic center of inversion. In addition, each Ni(II) ion also coordinates to one O atom from a benzo...

In this study, we demonstrate that synthetic dopa-melanin produced superoxide anions and promoted the peroxidative cleavage of phospholipids in the presence of Fe(3+)-ADP complexes. SOD significantly suppressed this lipid peroxidation, while catalase or sodium benzoate did not. During the reaction, MCLA-dependent chemiluminescence was detected, and this was suppressed to the control level by th...

In the title compound, [Co(C(7)H(3)Cl(2)O(2))(2)(C(10)H(8)N(2))(CH(3)OH)(2)](n), the Co(II) ion lies on a twofold rotation axis and is in a slightly distorted octa-hedral CdO(4)N(2) environment, formed by two O atoms from monodentate dichloro-benzoate ligands, two O atoms from methanol ligands, and two N atoms from trans-related 4,4'-bipyridine ligands. The bipyridine ligands also lies on a two...

The title compound, [Cu(C(8)H(7)O(2))(C(10)H(8)N(2))(2)]I·0.5H(2)O, was obtained by the hydro-thermal reaction of copper(I) iodide, 4-methyl-benzoic acid and 2,2'-bipyridine. The initial reactant of Cu(I) was oxidized to Cu(II). The asymmetric unit contains two independent complex mol-ecules, two I(-) ions and one water molecule. Each Cu(II) atom is coordinated by two O atoms from a 4-methyl-be...
