“…The liberated alkyl iodide was oxidized to HI03 and determined iodometrically. Pietrogrande, Bordin, and Fini (237) obtained correct methoxyl values on substances yielding low values by the Zeisel method by employing a methylimide apparatus and decomposing the sample with a mixture of hydriodic acid and ammonium iodide. Shah, Gobeille, and Mowery (270) modified the apparatus and procedure of Steyermark for micromethoxyl determination.…”
