Palladium-based hydrogenation catalyst decomposition and acetic anhydride is added immediately to the reaction vessel. Hydrocracking catalyst should not contain substantially water. The reaction vessel for the conversion of tetra-acetyl-dibenzyl hexa A wood Seoul Tze Tan ("TADB") The HBIW, hydrogen is introduced rapidly removed and an atmosphere capable of reacting with the hydrogen from the reaction vessel. To have no time to form an acetylated derivative of acetic anhydride reacts with the HBIW prior to the start of the hydrogenation reaction of interest, acetic anhydride is added immediately prior to the introduction of hydrogen. In this way, very small amount, palladium-based catalyst of 10% weight / weight only less than is required by standard HBIW substrate preferably. Been subjected to use formic acid solvent, the hydrogenation process of the second in the presence of hydrogen tetra-acetyl-diformylphenol hexa A wood Seoul Tze Tan TADB which has precipitated in palladium-based hydrogenation decomposition on the catalyst, the ("TADF") form."/>
