Two problems are present in the measurement of the exact quantities of catalyst used in hydrogenations with platinum oxide. The first arises from the fact that platinum oxide is highly adsorbent and rapidly gains weight due to adsorption of atmospheric components when it is exposed to air. A procedure is described for making an approximate correction for this weight gain. The second problem is the identity of the actual catalytic material. The observations indicate that this is platinum metal, and it is shown that the platinum content varies with the batch of catalyst.
