The crystal structure of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaiso-wurtzitane (CL-20) p-xylene solvate, and the solvent effects on the crystal faces of CL-20 were studied through a combined experimental and theoretical method. The properties were analyzed by thermogravimetry-differential scanning calorimetry (TG-DSC), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (...

Pseudomonas putida 39/D oxidized p-xylene to cis-3,6-dimethyl-3,5-cyclohexadiene-1,2-diol (cis-p-xylene dihydrodiol). The latter compound was isolated in crystalline form and its physical properties were determined. The cis configuration of the hydroxyl groups in the oxidation product was inferred from its ability to form an isopropylidene derivative with 2,2-dimethoxypropane. Acid treatment of...

Submit Manuscript | http://medcraveonline.com it can replace toluene where slower drying is desired. It is also a powerful cleaning agent, e.g., for silicon wafers, circuits and steel [1,2]. Toxicity of xylene in lung, thymus, liver and skin has been reported [3,4]. The nephrotoxicity of xylene has not been well documented. Cortical tubular epithelial cells are a vulnerable site of organic solv...

In a series of experiments to investigate interactions between industrial solvents and common medications the interaction between m-xylene and aspirin was studied. As both these substances are metabolised and excreted as glycine conjugates there would possibly be competition for this conjugation pathway. Five male volunteers were exposed on separate occasions to m-xylene by inhalation (100 ppm)...

Licochalcone A was isolated from the roots of Glycyrrhiza inflata and evaluated for its anti-inflammatory activity in xylene-induced mice ear edema and carrageenan-induced paw edema tests. At the same time, the inhibition of prostaglandin biosynthesis by licochalcone A was also studied in lipopolysaccharide (LPS)-induced mouse macrophage cells. At 5 mg/ ear, licochalcone A showed remarkable eff...

background: xylene is known as one of the most toxic of the nervous system. the purpose of this study is to estimate the concentration of xylene in the cabin of the vehicles production in iran. also the effect of ventilation, cigarette smoking, and air freshener inside the vehicle, fuel type and car decorations on the concentration of the substance being studied.   methods: 152 vehicles pride a...

Distribution of Inhaled m-Xylene in Rat Brain and its Effect on GABAA Receptor Binding: Takehiko ITO, et al. Faculty of Education, Okayama University—Organic solvents generally depress the central nervous system (CNS), similarly to volatile anesthetics. The precise mechanism of their action on the CNS, however, is not fully understood, and remains to be clarified. This study is focused on how i...

Each of twelve volunteers, at 2 week intervals, received 1 g of antipyrine, a test drug, and were exposed for 4 h either to toluene (375 mg/m3) or xylene (435 mg/m3) singly or in combination with ethanol (0.45 g/kg body wt. before the onset of exposure and 0.15 g/kg thrice every 1 h during exposure to maintain a steady level of ethanol in blood approximately 11 mmol/dm3). No significant differe...

Blood concentrations of 11 volatile organic compounds (VOCs) were measured up to four times over 2 years in a probability sample of more than 150 children from two poor, minority neighborhoods in Minneapolis, Minnesota. Blood levels of benzene, carbon tetrachloride, trichloroethene, and m-/p-xylene were comparable with those measured in selected adults from the Third National Health and Nutriti...

Molecular sieving MFI-type zeolite membranes were prepared by a secondary growth method without using an organic template. Silicalite membranes with intercrystalline pores minimized or eliminated were obtained by this synthesis method which avoids the template removal step. The silicalite membrane exhibits molecular sieving characteristics with pervaporation separation factor for p-xylene to o-...
