| titleOfInvention | PROCESS FOR PRODUCING PHOSPHORIC ACID |
| abstract | THE PRESENT INVENTION RELATES TO THE TRANSFORMATION OF PHOSPHATES AND RELATES MORE PRECISELY TO A PROCESS FOR THE PRODUCTION OF PHOSPHORIC ACID. THE PROCESS FOR THE PRODUCTION OF PHOSPHORIC ACID INCLUDES THE DECOMPOSITION OF PHOSPHATES BY SULFURIC AND PHOSPHORIC ACIDS UNTIL A PULP CONTAINING PHOSPHORIC ACID AND SEMI-HYDRATE CALCIUM SULPHATE OR SEMI-HYDRATE DIHYDRATE OR DIHYDRATE DIHYDRATE THE SAID PULP OF THE FINAL PRODUCT. FOLLOWING THE INVENTION THE DECOMPOSITION OF THE INITIAL PHOSPHATES IS CARRIED OUT BY A MIXTURE OF SULFURIC ACIDS, PHOSPHORIC ACIDS AND A PART OF THE SAID PULP WHICH IS RECYCLED AT THE DECOMPOSITION STAGE, WITH AIR IN THE FORM OF A DISPERSED SYSTEM , IN A WEIGHT RATIO OF THE DISPERSE PHASE AND THE DISPERSION MEDIUM OF 10.09 TO 0.16 RESPECTIVELY; OR ACCEPTED SEPARATELY IN THE FORM OF DISPERSED SYSTEMS OF A MIXTURE OF SULFURIC AND PHOSPHORIC ACIDS WITH AIR, IN A WEIGHT RATIO OF THE DISPERSE PHASE AND DISPERSAL MEDIUM OF 10.2 TO 0.3 RESPECTIVELY AND THE SAID RECYCLING PULP WITH AIR IN A WEIGHT RATIO OF 10.07 TO 0.06 RESPECTIVELY, OR BY A MIXTURE OF SULFURIC AND PHOSPHORIC ACIDS WITH AIR IN THE FORM OF A DISPERSED SYSTEM, IN A RATIO IN WEIGHT OF THE DISPERSE PHASE AND THE DISPERSAL MEDIUM FROM 10.1 TO 0.55. THE CLAIMED PROCESS WILL FIND WIDE APPLICATIONS IN THE MANUFACTURING OF FERTILIZERS, FORAGES, POLYMERS, FOR THE EXTRACTION OF URANIUM FROM ITS ORES, THE MANUFACTURE OF TENSIO-ACTIVE DERIVATIVES, PHARMACEUTICAL PRODUCTS, SYNTHETIC PRODUCTS, PESTICIDES, YEAST SUBSTITUTE PRODUCTS IN THE BIOCHEMICAL INDUSTRY. |
