Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3. It is a highly flammable, colorless liquid with an odor similar to that of gasoline . This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene , the precursor to polystyrene , a common plastic ...
[1] [2] Mass spectra is a plot of relative abundance against mass-to-charge ratio. It is commonly used for the identification of organic compounds from electron ionization mass spectrometry. [3] [4] Organic chemists obtain mass spectra of chemical compounds as part of structure elucidation and the analysis is part of many organic chemistry ...
Phase behavior Triple point: 278.5 K (5.4 °C), 4.83 kPa Critical point: 562 K (289 °C), 4.89 MPa Std enthalpy change of fusion, Δ fus H o: 9.9 kJ/mol at 5.42 °C
[3] [7] Commercial or laboratory-grade xylene produced usually contains about 40–65% of m-xylene and up to 20% each of o-xylene, p-xylene and ethylbenzene. [8] [9] [10] The ratio of isomers can be shifted to favor the highly valued p-xylene via the patented UOP-Isomar process [11] or by transalkylation of xylene with itself or trimethylbenzene.
In mass spectrometry, fragmentation is the dissociation of energetically unstable molecular ions formed from passing the molecules mass spectrum.These reactions are well documented over the decades and fragmentation patterns are useful to determine the molar weight and structural information of unknown molecules.
Another one of its cofounders helped the FBI unlock the iPhone used by one of the suspects in the 2015 San Bernardino mass shooting attack. Trump granted Wade clemency near the end of 2020, with ...
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Tiki, a 20-year-old blind cat from New England, was rescued by Good Samaritans after floating on a piece of ice on a Massachusetts lake and falling in on Dec. 16, 2024.
