Aplicación

Catalizador para:
  • Reacción de Stille
  • Reacciones de hidrogenación
  • Reacción de acoplamiento cruzado de Suzuki-Miyaura y reacciones de Heck-Mizoroki
  • Desoxigenación
  • Reacciones de oxidación
  • Reacciones de acoplamiento
El paladio sobre carbono (Pd/C) (carga 10 peso %, soporte matriz de carbón activado) puede utilizarse como catalizador en reacciones bien conocidas como las de hidrogenación de alquenos, alquinos, cetonas, nitrilos, iminas, azidas, grupos nitro, benzenoides y heterocíclicos aromáticos; la de hidrogenólisis de ciclopropanos, bencilderivados, epóxidos, hidracinas y haluros; y las de deshidrogenación aromática y deformilación de aldehídos.
También puede utilizarse como

  • catalizador para la hidrodecloración del diclorodifluorometano (CCL2F2), que es un gas de efecto invernadero conocido[1],
  • catalizador de las reacciones de Heck de haluros de arilo en líquidos iónicos[2]
  • catalizador anódico para la fabricación de pilas de combustible de ácido fórmico directo (DFAFC)[3]
  • electrocatalizador rentable para la oxidación del metanol[4]
  • en la hidrogenación catalítica de hidruros químicos para la producción de hidrógeno[5]
  • catalizador en la reacción de Suzuki-Mayaura[6]
El producto puede utilizarse con nuestro generador de hidrógeno de sobremesa, H-Genie Lite (Z744083)

Questions

1–10 of 11 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.
      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

  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
