The adsorption of CH3OH on such commonly used materials as quartz, pyrex, polytetrafluoroethylene teflon, petheoroalcoxy teflon and polished stainless steel SS316 is measured. Kinetic simulation can explain the experimental results, thus providing a basis for the generalization of the experimental results. The adsorption property of the materials at reduced temperature is also studied.展开更多
By using photoacoustic calorimetry, a photoacoustic measurement system is applied to determine the Co-C bond dissociation energy of n C4H9Co(Salen)H2O, which is 116±8kJ·mol-1.

This value is in agreement with the activation enthalpy of the Co-C bond homolytic cleavage reaction that obtained by the kinetic method.展开更多
