    摘要: THE CONVERSION OF S-HYDRINDACENE TO AS-HYDRINDACENE, OR THE REVERSE CONVERSION, IS EFFECTED BY CONTACTING A FEED RICH IN ONE OF THESE ISOMERS WITH HF-BF3 OR HF-BCL3 TO FORM THE OTHER ISOMER BY ISOMERIZATION. THESE ISOMERS ARE USEFUL AS INTERMEDIATES FOR THE PREPARATION OF BENZENE TETRACARBOXYLIC ACIDS OR THEIR ANHYDRIDES, WHICH PRODUCTS HAVE KNOWN UTILITY AS MONOMERS IN POLYMER MANUFACTURE.
