Procedure
The anthraquinone model compound (1,5-anthraquinonedisulfonic acid, disodium salt) and two polymers were subjected to the hydrogenation conditions. The reaction mixtures were analyzed with UV/visible spectroscopy following removal of the catalyst under an inert atmosphere (argon or nitrogen). Where anthrahydroquinone is formed, a bright yellow solution results. The results of some of the hydrogenation experiments are determined from the absorption spectra both before and after hydrogenation, and are summarized in Table 4.
