WebPhase analysis (XRD) verification was performed on the particulate at pH 5 in which diffraction peaks were attributed to Copper structure planes (with dimensions of 1042–3.34 nm) and other CuO ... Webthe biphenyl but not the triphenylmethanol. Decant the liquid & rinse the solids with another 2ml of petroleum ether. 18. Add the liquid to the 10 ml portion. Obtain the pure biphenyl (as a side product) by evaporating the petroleum ether over a hot plate. 19. Obtain an IR spectrum of triphenylmethanol (no need of drying for IR purpose). Leave the WebTheir structures were elucidated through extensive spectroscopic analysis. The three new compounds were elucidated as two new spiroketones, nitidaones A (1), and B (2) and one new biphenyl analog, nitidaol (3). The known compounds were identified as nordihydroguaiaretic acid (4), 7,3′,4′-tri-O-methylquercetin (5) and ayanin (6). dwayne carpenter
