Abstract
Previous investigations have proven that the complex [Mn(III)Mn(IV)(mu -0)( 2) (mu -CH3COO)L] (ClO4-)(2) with L = 1,2-bis-(4,7-dimethyl-1,4,7-triazacyl onone 1-yl)-ethane is a powerful catalyst. In this study, the stability of the catalyst and the effect of recycling the filtrates of a catalyzed P sta ge are investigated. Recycling of the filtrate of a P-CAT stage to another P stage does not result in a secondary catalytic effect. Onthe other hand, no negative impact of filtrate recycling is found.
