General description

Nickel(II) acetylacetonate, known as bis(acetylacetonato)nickel(II) or Ni(acac)2, is a blue-green crystalline compound soluble in water. It finds application in catalysis, materials synthesis, and organic chemistry, playing a crucial role as a catalyst in various reactions and serving as an important precursor for the development of nickel-based nanomaterials and catalysts used in industrial processes and organic transformations.

Application

Nickel(II) acetylacetonate can be:   
  • Used as a precursor to synthesize Ni-based nanomaterials such as NiO/C nanocomposite and crystalline NiO nanoparticles via different synthetic methods like non-isothermal decomposition and solvothermal method.,·      
  • Used to prepare Ni catalysts such as Nickel(II) complexes, and hierarchical Ni/beta catalysts for various organictransformations.
  • Nickel(II) acetylacetonate has several applications in catalysis: It is used as a catalyst for the polymerization of olefins and transesterification reactions.    
  • Nickel(II) acetylacetonate can be employed as a catalyst to promote Michael additions.

Questions

1–2 of 2 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
