Allgemeine Beschreibung

Ethylenediamine (en) is a linear aliphatic diamine that can be synthesized by reacting ethanolamine and ammonia in the presence of zeolite catalyst.[1] Its effect as an allergen has been investigated.[2] It participates in the synthesis of metal chalcogenides[3] and thiogallates.[4]

Anwendung

Ethylenediamine (1,2-Diaminoethane, DAE) can be used as a reagent to prepare various metal ion complexes. For instance, DAE reacts with chromium(II) salts forms a Cr(II)/DAE complex, which is used as an efficient reducing agent for the reduction of primary alkyl halides to alkanes, and aryl bromides or iodides to arenes. This complex is also used to reduce β-substituted alkyl halides and epoxides to alkenes.[5]
DAE can also be used in the following reduction reactions:
  • DAE/Borane (1:1) complex is used as a highly selective reducing agent for the conversion of cinnamaldehyde to cinnamyl alcohol.[5]
  • DAE/Li complex is used as an efficient reagent for the reduction of alkenes, aromatic hydrocarbons, phenols, and alcohols.[5]

Ethylenediamine (en) has been used in the following process:
  • Synthesis of nucleus pulposus (NP)-like collagen-glycosaminoglycans (CG) core.[6]
  • Surface modification of epoxy-activated cryogel.[7]
  • Alteration of the surface of carbon nanoparticles (CNPs) to generate CNPs-ethylene.[8]
It may be used in the following studies:
  • Surface modification of triazolate-bridged metal-organic framework.[9]
  • As a solvent in the synthesis of ZnS (zinc sulfide) and ZnSe (zinc selenium) precursors by solvothermal process.[10]
  • As a reactant in the synthesis of Pd/C-ethylenediamine complex catalyst.[11]
  • As a chelating agent in the synthesis of β-Co(OH)2 nanocrystals.[12]
  • Synthesis of ethylenediamine-templated iron arsenates and fluoroarsenates.[13]
  • As a template agent and coordination agent in the synthesis of CdS (cadmium sulfide) nanocrystals.[14]

Questions

1–3 of 3 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

  3. The concentration of the solution

    1 answer

    1. This product is a neat or pure liquid with a reported density of 0.899 g/mL and a molecular weight of 60.10 g/mol. Assuming a 99.9% purity, the concentration is approximately 14.94 M. The molarity may be determined using the molecular weight, density, and lot specific purity as demonstrated in the calculation below:
      (Density x 1000 x w/w% / Molecular Weight)
