Help: How to determine whether the catalyst contains mercury in its higher form or in its lower form
Thread Content
The catalyst has been moved from the background to the foreground; I want to know whether it has become ineffective. Is there any effective way to determine the valence state of mercury in the catalyst? What do others do in this regard? It would be best to provide a physical method; thank you all
The failure or not of a catalyst is a complex issue, not merely a matter of the valence state of mercury. Mercuric chloride dissolves in water, whereas mercurous does not; this makes it easier to carry out your physical measurements, but the task remains challenging! Additionally, whether a reference point is needed for the removal and replacement of the catalyst, I still recommend deciding based on the actual results of production!
Generally, by considering both time and conversion rate, it should be possible to determine whether dumping is necessary.
I would like to ask how to determine the mass percentage of mercuric subchloride in a catalyst
The roasting method is commonly used, and atomic absorption spectroscopy is also employed.
Baking method? Could someone explain it in detail? Thank you
HG/T 3468-2000 Chemical Reagent: Mercuric Chloride can be used for detection and analysis!
