, the temperature is varied by heating at a constant rate (β) with respect to time. Instead of employing a single heating rate, ‘multi-heating rate’ iso-conversional methods are employed to obtain more reliable kinetic results. These model-free methods

Introduction Catalytic conversion of methane into aromatics has been an interesting subject for the beneficial utilization of natural gas [ 1 ]. In this way, methane can be selectively converted to aromatics such as benzene and

comparison between experiments using nitrogen or air as purge gas. The thermal properties of photo-polymerized samples were studied by modulated temperature DSC (MTDSC). Complementary FT-IR measurements were carried out to evaluate the conversion of the

heating rates and the results were compared with the data obtained from isothermal dilatometric tests. Finally, the conversion degree for any isothermal treatment was calculated starting from the parameters obtained by non-isothermal dilatometric

-reversing are used to identify the processes reflected in the HF rev and HF nonrev signals, respectively. Curing reaction studies performed by DSC are based on total heat flow measurements, which allows for calculation of the conversion degree, α

/alkyl halides is the usual synthetic method [ 2 – 4 ]. Although, the conversion appears simple, the synthetic method is limited due to the storage of the toxic aryl/alkyl halides and the generation of undesired equimolar amounts of waste salts. The direct
