Analyse structurale du système acylant [CCl3CCO2H - (CH3CO)2O] Caractérisation des ions trichloroanhydridium et anhydridium acétiques
Written by sctunisie no commentsSpectroscopic analysis of the acylant system formed by trichloroacetic acid and acetic anhydride shows the presence of the following species : acetic trichloroanhydridium and acetic anhydridium ions under cyclic chelate shape. The survey of a set of solutions, that variable relative molar fractions, of this acylant system shows that the equilibrium of formation of these ions depends on the initial concentration ratio of the two interactive reagents: [Cl3CCO2H]0 / [(CH3CO)2O]0.
