A solution of 133 grams of 2,5-bis(4-dodecylbenzoyl)terephthalic acid and 1 L of tetrahydrofuran was treated with 8 grams of 10% palladium on carbon (as a catalyst) and heated to 65° C. for 17 hours in an atmosphere of hydrogen at 270 kPa. The mixture was filtered through Celite™ diatomaceous earth filter agent to remove the catalyst. The filtrate was concentrated in vacuo to give a solid. The solid was triturated with ethyl acetate, and the residue was dried to give 2,5-bis(4-dodecylbenzyl)terephthalic acid.
