一般說明

二乙醇胺（DEA）是一种常用于制备肥皂和表面活性剂、农用化学品和纺织加工中的氨基醇。[1]它可用作捕获CO2的吸收剂。[2]它的毒性和致癌作用已有研究。[1]

應用

二乙醇胺已被用于：
  • 作为合成氧化锌（ZnO）：铟（In）薄膜的溶剂和稳定剂，该薄膜可用作染料合成太阳能电池（DSSC）中的光阳极。[3]
  • 制备二乙醇胺底物缓冲液。[4]
  • 与MgCl2一起制备pH10的缓冲溶液，以用于孵育从星形胶质细胞培养物中提取的细胞裂解物。[5]
它可用于以下过程：
  • 通过脱氢制备二亚氨基二乙酸。[6]
  • 作为三嗪基树枝状大分子合成中的溶剂和反应物。[7]
  • 用于二乙醇胺离子液体的制备，以进行绿色Heck反应。[8]

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
