TL;DR: In this article, poly(ethylene terephthalate) (PET) pyrolysis products and those produced from their subsequent catalytic reactions under various metal oxides (ZnO, MgO, TiO2, and ZrO2) were evaluated qualitatively.

TL;DR: In this paper, the predictive capability of an existing detailed chemical kinetic model was evaluated for the thermal conversion rates of aromatic hydrocarbons in the presence of hydrogen and steam in a tubular flow reactor (total pressure of 160kPa, temperature of 1073-1673 K, and residence time of up to 1 s).

TL;DR: In this article, a comparison of ion concentrations measured by visible spectroscopy and spin concentration measured by spin resonance indicates that the aromatic ions in the solids are the only paramagnetic species present.
Abstract: Mixtures of aromatic hydrocarbons with antimony pentachloride in carbon tetrachloride have been studied by the methods of electron spin resonance and visible spectroscopy. The observation of a Tyndall effect and the spectroscopic properties show that the mixtures are colloidal suspensions. The visible spectra are characteristic of aromatic ions and a comparison of ion concentrations measured by visible spectroscopy and spin concentrations measured by spin resonance indicates that the aromatic ions in the solids are the only paramagnetic species present. The solids were found to exhibit high electronic conductivity.

TL;DR: Several triarylsulphonium and diaryliodonium compounds have been synthesised and the ability of the compounds to sensitise the polymerisation of epoxy resins was found to be dependent upon the counterion (hexafluorophosphates being more efficient than tetrafluoroborates) and upon the structure of the cation as mentioned in this paper.

TL;DR: In this paper, several strains were found to produce a large amount of cumic acid from p-cymene, including S449B1, B2, B3, B4 and B6.
Abstract: During the course of an investigation of the microbial assimilation of aromatic hydrocarbons, several strains were found to produce a large amount of cumic acid from p-cymene.Five strains, S449B1, B2, B3, B4 and B6, were isolated from soil with the aromatic hydrocarbon substrates. They all assimilated both p-cymene and cumene. The strain S449B3 grew also on p-xylene, and S449B6 on p-xylene, toluene, and ethylbenzene.They were all shown to be capable of producing an ultraviolet-absorbing substance from p-cymene. This substance was isolated in crystalline form and identified as cumic acid by infrared absorption spectrum and other observations.The superior strain, S449B6, produced the acid as much as 1000 mg/1 in shaking culture at 30°C after 24 hours. The yields were increased up to approximately 1700 mg/1 after further investigations. Addition of calcium carbonate and considerable agitation were favorable conditions for the acid production.The taxonomical studies of these strains were carried out, and they...
