Procedure

A mixture of 109 grams of 2,5-bis(4-nonylbenzoyl)terephthalic acid, 1500 mL of tetrahydrofuran, and 7.43 grams of 10% palladium on carbon (as a catalyst) was heated at 65° C. for 17 hours in an atmosphere of hydrogen at 270 kPa. The reaction mixture was filtered through Celite™ diatomaceous earth filter agent to remove the catalyst. The filtrate was concentrated in vacuo to give 2,5-bis(4-nonylbenzyl)terephthalic acid.
