Questions

1–8 of 8 Questions  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  4. Is Product 206032, Platinum (IV) oxide, water soluble?

    1 answer
    1. It is insoluble in water.

      Helpful?

  5. Are there any safety concerns with Product 206032, Platinum (IV) oxide?

    1 answer
    1. After exposure to hydrogen, the resulting platinum black can be pyrophoric.  Therefore, it should not be allowed to dry and all exposure to oxygen should be minimized.

      Helpful?

  6. How can Product 206032, Platinum (IV) oxide, be used as a catalyst?

    1 answer
    1. Platinum(IV) oxide can be used as a catalyst in hydrogenations.  The actual catalyst is platinum black which is formed in situ by reduction of the PtO2 by the hydrogen used for the hydrogenation.  It is especially useful for reduction at room temperature and hydrogen pressures up to 4 atmospheres.  It is suitable for the reduction of double and triple bonds, aromatic nuclei, carbonyl groups, nitro groups, and nitriles.

      Helpful?

  7. In which solvents is Product 206032, Platinum (IV) oxide, soluble?

    1 answer
    1. Per the the chemicals encyclopedia published by the Royal Society of Chemistry, 13th Edition, when freshly precipitated, Platinum(IV) Oxide is soluble in concentrated acids and dilute phosphoric acid, especially when warmed.  It is easily soluble in dilute solutions of potassium hydroxide.

      Helpful?

  8. Can the Platinum be recovered from Product 206032, Platinum (IV) oxide?

    1 answer
    1. Internet sources do indicate that Platinum can be recovered from spent catalyst by conversion to ammonium chloroplatinate using aqua regia followed by ammonia.  However, we do have a process for doing so.
