Measuring hydroperoxide chain-branching agents during n-pentane low-temperature oxidation

Detailed product analysis during the low temperature oxidation of n-butane.

The products obtained from the low-temperature oxidation of n-butane in a jet-stirred reactor (JSR) have been analysed using two methods: gas chromatography analysis of the outlet gas and reflectron time-of-flight mass spectrometry. The mass spectrometer was combined with tunable synchrotron vacuum ultraviolet photoionization and coupled with a JSR via a molecular-beam sampling system. Experime...

Autocatalytic Decomposition of Cumene Hydroperoxide at Low Temperature Conditions

Cumene Hydroperoxide (CHP) has been used in the production of Dicumyl Hydroperoxide (DCPO) and phenol. In Taiwan, several severe fire or explosion incidents have occurred due to its thermal instability or reactivity. In this research, the exothermic decomposition of CHP in Cumene was characterized by isothermal microcalorimeter, TAM (thermal activity monitor), because isothermal testing offers ...

Development of a Low-temperature Catalytic Oxidation System for Destruction of Chemical Warfare Agents

This project is to develop a low-temperature microwave catalytic oxidation system that will effectively decontaminate air containing aerosolized or gaseous chemical agents (CWAs). To protect personnel in shelters, catalytic oxidation systems should (1) destroy CWAs in air at low temperatures to avoid NOx formation, (2) remove sulfur dioxide produced from the oxidation of CWAs containing sulfur ...

A model-free temperature-dependent conformational study of n-pentane in nematic liquid crystals.

The proton NMR spectra of n-pentane orientationally ordered in two nematic liquid-crystal solvents are studied over a wide temperature range and analysed using covariance matrix adaptation evolutionary strategy. Since alkanes possess small electrostatic moments, their anisotropic intermolecular interactions are dominated by short-range size-and-shape effects. As we assumed for n-butane, the ani...
