Volatile Profiles of Emissions from Different Activities Analyzed Using Canister Samplers and Gas Chromatography-Mass Spectrometry (GC/MS) Analysis: …
2017
The objective of present study was to identify volatile organic compounds (VOCs) emitted from several sources (fuels, traffic, landfills, coffee roasting, a street-food laboratory, building work, indoor use of incense and candles, a dental laboratory, etc.) located in Palermo (Italy) by using canister autosamplers and gas chromatography-mass spectrometry (GC-MS) technique. In this study, 181 VOCs were monitored. In the atmosphere of Palermo city, propane, butane, isopentane, methyl pentane, hexane, benzene, toluene, meta- and para-xylene, 1,2,4 trimethyl benzene, 1,3,5 trimethyl benzene, ethylbenzene, 4 ethyl toluene and heptane were identified and quantified in all sampling sites.

Headspace–mass spectrometry determination of benzene, toluene and the mixture of ethylbenzene and xylene isomers in soil samples using chemometrics
2007
A simple and fast method has been developed for the determination of benzene, toluene and the mixture of ethylbenzene and xylene isomers (BTEX) in soils. Samples were introduced in 10 mL standard glass vials of a headspace (HS) autosampler together with 150 microL of 2,6,10,14-tetramethylpentadecane, heated at 90 degrees C for 10 min and introduced in the mass spectrometer by using a transfer line heated at 250 degrees C as interface. The volatile fraction of samples was directly introduced into the source of the mass spectrometer which was scanned from m/z 75 to 110. A partial least squares (PLS) multivariate calibration approach based on a classical 3(3) calibration model was build with m…
Development of a simulation chamber for the evaluation of dermal absorption of volatile organic compounds
2020
Abstract An exposition chamber has been designed and developed for the production of contaminated atmospheres with fixed and known concentration of volatile organic compounds. The proposed chamber has been evaluated for the determination of in-vitro diffusion parameters, such as flux and lag time for benzene, toluene, ethylbenzene, and xylenes (BTEX). Polydimethylsiloxane (PDMS) and Strat-M® membranes were evaluated, including the effect of membrane thickness, from 0.5 to 3.0 mm, on the diffusion parameters. The obtained flux values and lag times, ranged from 0.2 to 1.5 μg cm−2 h−1 and from 10 to 130 min, respectively, for studies performed at a BTEX concentration of 51 μg L−1 in air. Diffe…
Studien zum Vorgang der Wasserstoffübertragung, 54. Mechanismus und Grenzen der Clemmensen-Reduktion des Acetophenons und verwandter Verbindungen
1978
Bei der Reduktion von Acetophenon nach Clemmensen entstehen auser Ethylbenzol (1; Vier-Elektronen-Ubergang) in von den Reaktionsbedingungen abhangigen Mengen das Hydrodimerisierungsprodukt 2,3-Diphenyl-2,3-butandiol (2; Ein-Elektronen-Ubergang) und dessen Umlagerungsverbindungen 3 und 4, aber weder 1-Phenylethanol noch Styrol (Zwei-Elektronen-Ubergang). Temperatur, Saurekonzentration, Saureart, Reduktionsmittel (amalgamiertes Zink, Zinkamalgam, Cadmium, Zink-Cadmium-Legierung, Cadmiumamalgam, Magnesiumamalgam, Blei, Zink, Blei-Legierung) bestimmen die Anteile der gebildeten Reduktionsprodukte 1 — 4. 1-Phenylethanol und Styrol konnen unter Clemmensen-Bedingungen partiell in Ethylbenzol (1) u…
