| titleOfInvention | Continuous production of anthranilic acid |
| abstract | 1. A PROCESS FOR THE CONTINUOUS PRODUCTION OF ANTHRANILIC ACID WHICH COMPRISES REACTING A STRATING COMPOUND SELECTED FROM THE GROUP CONSISTING OF THE ALKALI METAL SALTS OF PHTHALAMIC OF STAGES, THE FRIST REACTION AQUEOUS MEDIUM IN A PLURALITY OF STAGES, THE REACTION STAGES FOR CONVERTING THE STARTING COMPOUND INTO THE ALKALI METAL SALT OF PHENYL ISOCYANATE-2-CARBOXYLIC ACID BEING CARRIED OUT UNDER SUBSTANTIALLY ADIABATIC CONDITIONS WHILE SUBSTANTIALLY AVOIDING ANY BACKMIXING, THE RESULTING REACTION MIXTURE BEING IMMEDIATELY WITHDRAWN FROM THE REACTION ZONE OF SAID FIRST STAGES AND THEN SUPPLIED SUBSTNATIALLY WITHOUT BACKMIXING TO THE REACTION ZONE OF AT LEAST ONE SUBSEQUENT STAGE FOR HYDROLYSIS AND DECARBOXYLATION OF SAID PHENYL ISOCYANATE-2-CARBOXYLIC ACID INTO ANTHRANILLIC ACID, A REDUCING AGENT SELECTED FROM THE GROUP CONSISTING OF SODIUM BOROHYDRIDE, LITHIUM TRIETHOXY ALUMINUM HYDRIDE, SODIUM SULFIDE, SODIUM HYDROGEN SULFIDE, AMMONIUM SULFIDE, SULFUROUS ACID, SULFUR DIOXIDE, SODIUM DITHIONITE, SODIUM, THIOSULFATE, SODIUM FORMALDEHYDE SULFOXYLATE, THIOUREA DIOXIDE, HYDRAZINE AND ITS SALTS, GLUCOSE SODIUM SULFITE AND SODIUM BISULFATE BEING ADDED TO THE REACTION MIXTURE WITHDRAWN FROM THE REACTION ZONE OF SAID FIRST STAGES AND BEFORE THE REACTION HAS BEEN COMPLETED. |
