PROCEDURE FOR THE PREPARATION OF ZINC OR ALUMINUM PHTHALOCYANINE COMPOUNDS. FORMULA PHTHALOCYANIN (MOPC) R <018> IS REACTED WITH CHLOROSULPHONIC ACID, HYDROLYZING THE RESULTING SULFOCLORIDE, OPTIONALLY CAN BE SULFONATED WITH OLEUM. COMPOUNDS OF GENERAL FORMULA (I) ARE OBTAINED IN WHICH MEPC IS A CYCLIC SYSTEM OF PHTALOCIANIN OF ZINC OR ALUMINUM; AND MEANS HYDROGEN OR AN ALKALINE METAL ION OF AMMONIUM OR AMINE SALT; V IS A NUMBER SUCH AS 0, 1 OR 4; R MEANS FLUORINE, BROMINE, IODINE OR CYANE; X IS 0, 1 OR 8. WHITENING TAKES PLACE AT PREFERRED TEMPERATURES OF 20 TO 85 <025> C OVER THE TIME OF 15 TO 60 MINUTES. > WHITENE OR REMOVE STAINS OF TEXTILE GENRES AS WELL AS COMBAT THE MICROORGANISMS THAT THEY CONTAIN. |
