摘要

PROCESS FOR THE ELABORATION OF 4 SULFONIL BENZOLES OF THE FORMULA (1) WHERE R1, R2 EQUAL OR DIFFERENT REPRESENT (C1 ZOSULFON ACID CHLORHIDRICO OF THE FORMULA (2) WHERE R1 HAS THE MEANING GIVEN BEFORE, IT IS TRANSFORMED WITHIN MORE CHLORINE IN THE PRESENCE OF A CHLORINE TRANSFER AT A TEMPERATURE FROM APPROXIMATELY 50 TO 100 OPPOSITE OF THE GENERAL FORMULA (3) WHERE R1 WHICH HAS THE MEANING GIVEN BEFORE, BEING CHLORINATED, DUE TO SODIUM SOUTHWATER WITH SULA SODIUM SULPHITE IN TEMPERATURE FROM APPROXIMATELY 40 TO 90 RA TO OBTAIN A COMPOUND OF THE GENERAL FORMULA (4) WHERE R1 HAS THE MEANING ALREADY GIVEN, IT IS REACTED WITH A NERAL ALPHA (5) WHERE R1 IS OIDRO (C1 OMO OR CHLORINE, OR ONE OF ITS SALTS, TO OBTAIN THE 4 UIL INITIALLY, OR ONE OF ITS SALTS IS CONDEMNED AND THEN IT IS DECARBOXYLATED THROUGH WARMING. THE INVENTION FURTHER REFERS TO COMPOUNDS OF THE FORMULA (1), WHERE R1 MEANS (C1 QUIL AND R2 (C1 (4) WHERE R1 IS MEAN (C1 C4) THESE OF THE FORMULA (6) WHERE R IS EQUAL TO HYDROGEN OR (C1 NORTH ALKALINE METAL SALTS.
