一般說明

乙二胺是一种线性脂肪族二胺，可用通过乙醇胺和氨在沸石催化剂的存在下反应获得。[1]它作为过敏源，已经被研究过了。[2]它参与金属硫族化合物[3]和硫代镓酸盐的合成。[4]

應用

乙二胺(1，2-二氨基乙烷，DAE)可用作制备各种金属离子络合物的试剂。例如，DAE与铬（II）盐形成Cr(II)/DAE络合物，该络合物可作为高效还原剂用于将伯烷基卤化物还原为烷烃，以及将芳基溴化物或碘化物还原为芳烃。这种络合物还可以用于 β-取代的烷基卤化物和环氧化物还原为烯烃。[5]
DAE还可用于以下还原反应：
  • DAE/硼烷 （1：1）络合物可用作高选择性还原剂，用于将肉桂醛转化为肉桂醇。[5]
  • DAE/Li络合物被用作高效试剂用于还原烯烃，芳香烃，酚类和醇类。[5]

乙二胺可以用于下列实验：
  • 合成髓核（NP）样胶原氨基聚糖（CG）核。[6]
  • 表面修饰环氧树脂激活冷冻剂。[7]
    • 改变碳纳米颗粒（CNPs）表面产生CNPs-乙烯。
  • [8]
它还可用于以下研究：
  • 表面修饰三唑桥金属有机框架。[9]
  • 作为ZnS（硫化锌）和ZnSe（硒化锌）前体溶剂热法合成的溶剂。[10]
  • 作为Pd/C-乙二胺复合体催化剂的反应试剂。[11]
  • 在β-Co(OH)2 纳米晶体合成过程中作为螯合剂。[12]
  • 合成乙二胺模板砷酸铁和氟砷酸盐[13]
  • 作为合成CdS（硫化镉）纳米晶体的模板试剂和配位剂。[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)
