Reactivity of the Ozone−Ethane System

Abstract

The reaction of ozone with ethane was studied in the range 24−150 °C. Added oxygen at 24 °C was found to cause a large induction period after which the reaction occurred rapidly accompanied by a flash of light. The light consisted of Meinel bands from vibrationally excited OH radicals as had been previously seen at higher temperatures in the methane−ozone system. Induction periods of more than 3 h were measured when an excess of oxygen was added. Total pressure measurements suggested a chain reaction, and several possible chain sequences are considered. A 42-step mechanism was used to simulate the system and found to account for the effect of added oxygen on the induction period and on the light emission.

Influence of plasma reactor structure on methanol oxidation

“…O 3 acted as a carrier to yield O and OH (Eqs. 16–18)27—both radicals play important parts in CH 3 OH oxidation as described above.…”

Gas-liquid-liquid reactions: Contacting mechanisms and effective process technologies

“…Firstly, ozone has greater solubility in an organic solvent than in edible oil [27], [28]. Secondly, ozone is much more reactive with carbon compounds [29], [30] that have double bonds than those with a single bond [11], [31]. For example, the ozonolysis reaction of waste cooking oil (WCO) in Table 1 consists of three-phases: methanol, FFA and ozone [14].…”
