Abstract
Various embodiments disclosed relate to bridged phthalocyanine- and napththalocyanine-metal complex catalysts and methods of using and purifying the same. In various embodiments, the present invention provides a method of purifying a catalyst. The method includes contacting a catalyst composition with acid, the catalyst composition including a catalyst, to provide an acidified catalyst composition with the catalyst dissolved therein. The method includes precipitating the catalyst, and removing the precipitated catalyst from solution, to provide a purified catalyst.
Claims19
A method of purifying a catalyst, the method comprising:
- contacting a catalyst composition with acid, the catalyst composition comprising a catalyst, to provide an acidified catalyst composition with the catalyst dissolved therein, the catalyst having the structure:
- wherein
- M is a metal,
- axial ligand L is a solvent molecule,
- at each occurrence, RA and RB are independently chosen from —H, halide, an organic group, and a hydrophilic group, or RA and RB together form a fused aromatic ring with the ring upon which RA and RB are substituted, RA and RB together having the structure:
- and
- at each occurrence, R1, R2, R3, R4, R5, and R6 are each independently chosen from —H, halide, an organic group, and a hydrophilic group;
- precipitating the catalyst;
- and
- removing the precipitated catalyst from solution, to provide a purified catalyst.
A purified catalyst having the structure:
- wherein
- M is a metal,
- axial ligand L is a solvent molecule,
- at each occurrence, RA and RB are independently chosen from —H, halide, an organic group, and a hydrophilic group, or RA and RB together form a fused aromatic ring with the ring upon which RA and RB are substituted, RA and RB together having the structure:
- at each occurrence, R1, R2, R3, R4, R5, and R6 are each independently chosen from —H, halide, an organic group, and a hydrophilic group, wherein at each occurrence, the hydrophilic group is independently chosen from —C(O)OH, —O—C(O)OH, —P(O)(OH)2, —OP(O)(OH)2,—S(O)(O)OH, —OS(O)(O)OH, a salt thereof, a substituted or unsubstituted (C1-C50)hydrocarbyl ester thereof, and a combination thereof, and
- the purified catalyst is about 95 wt% pure to about 100 wt% pure.
A catalyst having the structure:
- wherein
- M is a metal,
- L is a solvent molecule, and
- at each occurrence, R1,R2, R3, R4, R5, and R6 are independently chosen from —H, halide, an organic group, and a hydrophilic group.
