Synthesis of manganese oxidation catalyst |
| abstract |
A process is described for the preparation of a manganese complex catalyst having formula (I) wherein Mn is manganese in a III or IV oxidation state; each X is independently a coordinating or bridging species; L is an organic ligand containing at least two nitrogen atoms that coordinate with the Mn; z is an integer ranging from -4 to +4; Y is a monovalent or multivalent counterion leading to charge neutrality; and q is an integer from 1 to 4. The process comprises two steps. In the first step a man-ganese (II) salt is reacted with the ligand L or precursor thereof in the presence of a counterion salt MzYq, where M is selected from metallic, ammonium and alkanolammonium ions. The resulting manganese coordinated substance is reacted with an oxidising agent at a pH of at least 12. The manganese complex catalyst is an active bleach catalyst. |
