Application

Lindlar catalyst is a heterogeneous catalyst that is used mainly for the selective hydrogenation of alkynes to alkenes.
It can also effective catalyze:
  • selective hydrogenations of triple bonds to cis-double bonds
  • monohydrogenation of polyolefins
  • hydrogenation of azides to amines

Components

~ 5% palladium on calcium carbonate; poisoned with lead.

Questions

1–3 of 3 Questions  
  1. 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.

  2. 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

  3. Hello I wanted to know whether there is difference in the composition of the Lindlar's catlalyst (Cat. No. 62145) and the palldium on calcium carbonate (Cat. No. 205737). Thank you

    1 answer
    1. The composition of each product consists of calcium carbonate, palladium, and lead in roughly the same amounts. However, the maximum allowable moisture content for the 62145 is 62 % while the maximum allowable for the 205737 is 4 %.
