The macro kinetic models of synthesis, hydrolysis and decomposition of PFA were investigated via formic acid-autocatalyzed reaction. It was found that the intrinsic activation energies of PFA synthesis and hydrolysis were 75.2 kJ·mol^-1 and 40.4 kJ·mol^-1 respectively. The observed activation energy of PFA decomposition was 95.4 kJ·mol^-1. The experi-mental results indicated that the decomposition of PFA was liable to occur even at the ambient temperature. Both the spontaneous decomposition and the radical-introduced decomposition contributed to the decomposition of PFA.展开更多

This suggests a relationship between corporations and society. In this study, that relationship is analyzed, specifically the relationship between levels of CSER and economic institutions. A strong link with institutions is an outcome of institutionalization. The economic institutions applied are economic freedom and legal origin as a proxy for national corporate governance systems. The results of this descriptive study show associations between CSER levels and economic freedom. CSER is also related to national corporate governance systems through legal origin. CSER appears to be institutionalized, or in any case, corporations seem to be aware of the economic institutionalization of CSER.展开更多
