Mass Spectral Studies to Investigate Butylbenzene Fragmentation Pathway and Pyrolysis Products.
… gas chromatography mass spectrometry of n-butylbenzene and pyrolysis products are presented. In the first study, fragmentation pathways of n-butylbenzene in quadrupole ion trap have been investigated. At low energy, product ion corresponding to m/z 92 and m/z 91 are formed via competitive …

X-Ray Crystal Structure of Au36(SPh-pCH3)24 Nanomolecules
… thiolate protecting ligand such as tert-butylbenzene thiol, thiophenol and cyclopentane thiol have been reported. It has been predicted that aromatic thiol protected Au36(SR)24 NM have same core structures like the other reported Au36(SR)24 NMs. Due to the steric and electronic …

Preparation, characterisation and modification of porous carbon monolithic materials for chromatographic and electrochemical applications
… preliminary separations of mixtures of butylbenzene– acetophenone, and butylbenzene-nitrobenzene, respectively, on a same column column were also carried out using a mobile phase of 100% hexane (or pentane), flow rate 1 ml/min, UV detection 254 nm, with an injection volume 15 μL. The …

The kinetics and solvent effects on the thermal decomposition of isopropyl peroxide and 1, 2-dioxane
… of thermal decomposition of 1,2-dioxane in tert-butylbenzene at l40o-l70oC have been determined. The activation energy was found to be 33.4 Kcal/mole. This lower activation energy, compared to that for the decomposition of isopropyl peroxide in toluene (39.1 Kcal/mole) has been explained in terms …

Reactions of some non-enolisable chloroketones with amide ion and a new synthesis of acridones /|nGuo-shyoung John Chen. -- 260 St. Catharines, Ont. : [s. n.],
… these two ketones with potassium t-butoxide in t-butylbenzene. i Section 2 deals with the investigation of the reaction of some tricyclic ch1orobenzophenones with potassium amide in liquid ammonia. These were 1-ch1orof1uorenone; which was pr~pared in several steps from f1uoranthene, and 1- and …

New chelating ligands: Applications to hydrodenitrogenation catalysis
… [2-(5-Trifluoromethylpyridyl)]-2-hydroxy-3,5-di-t-butylbenzene) ( 45) and 2-(2-pyridyl)phenol (46) were synthesized with the intent to form a ligand set that took advantage of the cyclometallation problem by putting a pyridine functionality in the position likely to be cyclometallated. Monomeric …

The effect of different chemical classes on the swelling of NBR O-rings in blends with synthetic paraffinic kerosene
… tetralin, over other C10 aromatics such as n-butylbenzene. Aromatic ethers caused significantly more swell than hydrocarbon aromatics. Some of these aromatic oxygenates swelled even more than petroleum-derived Jet A-1 even when used at the minimum 8% aromatic level. This was explained in terms …

Analysis of the potato sprout inhibitor 1, 4-dimethylnapthalene: HPLC method development and applications.
… (2-ethylnaphthalene, 1-ethylnaphthalene and n-butylbenzene) for the similarity of their behaviour to 1,4-DMN in the extraction and chromatographic separation processes. An aliquot of the 2,2,4-trimethylpentane layer was then analysed directly by HPLC. This method was validated in the range …
