| titleOfInvention | Process for the preparation of cyclic acid anhydrides |
| abstract | A PROCESS IS DEFINED FOR HEATING AN ORGANIC COMPOUND CONTAINING AT LEAST ONE HALF-ESTER OF A DICARBOXYLIC ACID WHERE THE CARBONYL GROUPS ARE DIRECTLY CONNECTED TO ADJACENT INTERNAL ALIPHATIC CARBON ATOMS TO A TEMPERATURE FROM ABOUT 80*C. TO 149*C. TO COVERT THE HALFESTER GROUPS TO CYCLIC ANYDRIDE GROUPS AND A BY-PRODUCT ALCOHOL. THE ORGANIC COMPOUND IS A 1:1 COPOLYMER OF AN ALIPHATIC HYDROCARBON HAVING AT LEAST THREE CARBON ATOMS, SUCH AS 1-HEXANE, AND MALEIC ANHYDRIDE. IF THE ORGANIC COMPOUND CONTAINS BOTH HALF-ESTER AND KIESTER GROUPS, THE RESULTING COMPOUND AFTER HEATING TO A TEMPERATURE FROM 80*C. TO 149*C. WILL CONTAIN ANHYDRIDE AND DIESTER LINKAGES. |
