Synthesis of novel vanadium porphyrin

Claim 1

A METHOD FOR PRODUCING VANADIUM TETRAPHENYL PORPHYRIN WHICH COMPRISES REFLUXING A MIXTURE OF A MINOR AMOUNT OF VANADIUM PENTOXIDE AND A MAJOR AMOUNT OF HYDROCHLORIC ACID, ADDING A SATURATED ALIPHATIC ALCOHOL CONTAINING 1 TO 4 CARBON ATOMS TO THE REFLUXING MIXTURE AND CONTINUING THE REFLUXING UNTIL A SOLUTION HAVING A CLEAR, BRIGHT, DEEP BLUE COLOR DEVELOPS, ADJUSTING THE PH OF THE SOLUTION TO A PH IN THE RANGE FROM ABOUT 6.0 TO ABOUT 7.0 TO FORM A PRECIPITATE, RECOVERING THE PRECIPITATE IN THE SUBSTANTIAL ABSENCE OF AIR, FORMING A SECOND ADMIXTURE OF THE PRECIPITATE WITH NAPHTHALENE AND TETRAPHENYL PORPHYRIN, SAID NAPHTHALENE AND TETRAPHENYL PORPHYRIN BEING IN THE RATIO OF AT LEAST ABOUT 6 TO 1, REFLUXING THE SECOND ADMIXTURE UNTIL A BRIGHT RED MELT IS OBTAINED, ADMIXING THE MELT WITH DISTILLED WATER TO FORM A THIRD ADMIXTURE, RECOVERING SOLID MATERIAL FROM THE THIRD ADMIXTURE, EXTRACTING THE SOLID MATERIAL WITH A SOLVENT SELECTED FROM THE GROUP CONSISTING OF THE ALIPHATIC ALCOHOLS AND ACETONE TO REMOVE NAPHTHALENE, EXTRACTING REMAINING SOLID MATERIAL WITH CHLOROFORM TO FORM A CHLOROFORM EXTRACT, DRYING THE CHLOROFORM EXTRACT TO FORM A RESIDUE, FRACTIONALLY EXTERACTING THE RESIDUE WITH A LOW BOILING AROMATIC HYDROCARBON TO FORM AN AROMATIC HYDROCARBON SOLUBLE PHASE AND A SOLID PHASE, AND SUBLIMING SAID SOLID PHASE TO OBTAIN VANADIUM TETRAPHENYL PORPHYRIN THEREFROM.

Claim 2

A METHOD FOR PRODUCING VANADIUM TETRAPHENYL PORPHYRIN WHICH COMPRISES REFLUXING A MIXTURE OF A MINOR AMOUNT OF VANADIUM PENTOXIDE AND A MAJOR AMOUNT OF HYDROCHLORIC ACID, ADDING A SATURATED ALIPHATIC ALCOHOL CONTAINING 1 TO 4 CARBON ATOMS TO THE REFLUXING MIXTURE AND CONTINUING THE REFLUXING UNTIL A SOLUTION HAVING A CLEAR, BRIGHT, DEEP BLUE COLOR DEVELOPS, ADJUSTING THE PH OF THE SOLUTION TO A PH IN THE RANGE FROM ABOUT 6.0 TO ABOUT 7.0 TO FORM A PRECIPITATE, RECOVERING THE PRECIPITATE IN THE SUBSTANTIAL ABSENCE OF AIR, FORMING A SECOND ADMIXTURE OF THE PRECIPITATE WITH NAPHTHALENE AND TETRAPHENYL PORPHYRIN, SAID NAPHTHALENE AND TETRAPHENYL PORPHYRIN BEING IN THE RATIO OF AT LEAST ABOUT 6 TO 1, REFLUXING THE SECOND ADMIXTURE UNTIL A BRIGHT RED MELT IS OBTAINED, ADMIXING THE MELT WITH DISTILLED WATER TO FORM A THIRD ADMIXTURE, RECOVERING SOLID MATERIAL FROM THE THIRD ADMIXTURE, EXTRACTING THE SOLID MATERIAL WITH A SOLVENT SELECTED FROM THE GROUP CONSISTING OF THE ALIPHATIC ALCOHOLS AND ACETONE TO REMOVE NAPHTHALENE, EXTRACTING REMAINING SOLID MATERIAL WITH CHLOROFORM TO FORM A CHLOROFORM EXTRACT, DRYING THE CHLOROFORM EXTRACT TO FORM A RESIDUE, FRACTIONALLY EXTERACTING THE RESIDUE WITH A LOW BOILING AROMATIC HYDROCARBON TO FORM AN AROMATIC HYDROCARBON SOLUBLE PHASE AND A SOLID PHASE, AND SUBLIMING SAID SOLID PHASE TO OBTAIN VANADIUM TETRAPHENYL PORPHYRIN THEREFROM.
