Abstract:
A very sensitive mass-spectrometry method has been developed for the analysis of aromatic amines in tobacco smoke and in indoor air. Cigarettes were smoked with a smoking machine; the anwies from the smoke were trapped in a 5% HCl water solution containing internal standards and detected by gas chromatography/mass spectrometry in the selected-ion-monitoring (SIM) mode. The amines measured were the following: aniline. 2-toluidine, 3-toluidine, 4-toluidine, 2-ethylaniline, 3-ethylaniline, 4-ethylaniline, 2,3-dimethylaniline, 2,4-dimethylaniline, 2,5-dimethylaniline, 2,6-dimethylaniline, 1-naphth

Primary aromatic amines were synthesized from the corresponding nitrobenzenes via photoinduced reduction. The reaction was found to be effective when nitrobenzenes with electron-withdrawing substituents were irradiated with a broad band of UV light centered at 306 nm. When reactions are completed, products could be isolated by acid–base extraction or by column chromatography. This presenting photoreaction procedure for the synthesis of primary aromatic amines from the corresponding nitrobenzenes proceeds without the need of a sensitizer in isopropanol or THF.

The (HCr(CO)$\sb5$) -anion in the form of its PPN$\sp+$ and Et$\sb4$N$\sp+$ salts also catalysed this reaction (under hydrogen) but was selective to the formanilide products.

Moreover, the partitioning of amines to the hydrocarbon phase can form corresponding amine chloride salts leading to the under deposit corrosion in the refinery units. In the present inv

Abstract Despite the widespread use of corrosion inhibitors (CIs) in the oil and gas industry much of their complex aggregation and adsorption behavior is still very poorly understood. CIs are surface active species meaning that when they are injected into aqueous solutions they naturally aggregate and migrate to gas-liquid, liquid-liquid, and solid-liquid interfaces. A better understanding of each CI component and how it adsorbs when exposed to various surfaces could lead to improved CI design, higher performance at lower dosages, as well as improved methods for residual detection.
