| titleOfInvention | Process for the production of pure aryl esters of dicarboxylic acids |
| abstract | A PROCESS FOR THE PRODUCTION OF ARYL ESTERS OF POLYCARBOXYLIC ACIDS SUCH AS ISOPHATHALIC AND TEREPTHALIC ACID IS DISCLOSED WHICH IS AN IMPROVEMENT IN THE PROCESS DISCLOSED IN U.S. PATENT 3,471,549. THE IMPROVEMENT OF THE SUBJECT PROCESS INVOLVES THE ADDITION OF A CARBONIC ACID DIARYL ESTER IN PLACE OF THE LOWER FATTY ACID ANHYDRIDE USED IN THE PROCESS OF THE PATENT. THE CARBONIC ACID DIARYL ESTER IS ADDED IN AN AMOUNT WHICH IS AT LEAST EQUIVALENT TO THE ALKYL ESTER GROUPS STILL PRESENT IN THE REACTION MIXTURE WHICH CONTAINS THE DESIRED ARYL ESTER OF THE POLYCARBOXYLIC ACID. |
