The reaction resulted in the formation of a polymeric solid fraction and the noncrosslinked properties of this material assisted in its characterization by solution state 13C and 19F nuclear magnetic resonance spectroscopy. Gel permeation chromatography revealed that the polymers include low (number average molecular weight, Mn values between 900 and 3000 g mol-1) and high (Mn approximately 60000 g mol-1) molecular weight fractions. A detailed polymerization mechanism is proposed, based on the published literature and the findings of the current investigation.]]> Sat 24 Mar 2018 07:56:56 AEDT ]]> Experimental study on the reaction of CCl₃F and CH₄ in a dielectric barrier discharge nonequilibrium plasma reactor https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26110 –1 (the applied voltage range was 14.1 to 15.2 kV, peak–peak). The electrical discharge was characterized and found to be a slight modification of filamentary discharge toward a diffuse discharge due to the presence of the relatively low concentration of CCl₃F and CH₄ (less than 2% each) in argon. A reaction mechanism is proposed describing the formation of gas phase, as well as polymeric products.]]> Sat 24 Mar 2018 07:39:53 AEDT ]]> Experimental investigation of the reaction of HCFC-22 and methane in a dielectric barrier discharge non-equilibrium plasma https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30335 -1 to 13 kJ L-1.

The relatively low input feed concentration of CCl₂F₂ and methane in the argon bath gas modifies the strong filamentary appearance of the pure argon discharge to a more diffuse appearance.]]> Sat 24 Mar 2018 07:25:59 AEDT ]]> Effect of methane on the conversion of HFC-134a in a dielectric barrier discharge non-equilibrium plasma reactor https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24020 -1 feed rate reduces the conversion of CF₃CH₂F from 74.5% to 46.8% and increases the formation of HF from 1500µmolh-1 to 2640µmolh-1. The effect of methane addition on the electrical discharge and the reaction pathways are discussed.]]> Sat 24 Mar 2018 07:16:44 AEDT ]]>
