一般說明

通常用作漂白剂和干燥剂的乙酸钴(II)四水合物可通过碳酸钴(II)与乙酸反应而制得。[1] 其在非等温条件下加热至500°C时会发生分解。[2] 其晶体表现出具有 P21/c空间群的单斜晶体系统。[3] 四水合乙酸钴(II)可与1,3,5-苯三甲酸(BTCH3)进行水热反应,从而生成Co3(BTC)2.12H2O。[4]

應用

乙酸钴(II)四水合物可用于制备[Co3(OH)2(H2O)2(aptet)4](aptet = 4-氨基苯基四唑酸酯)[5] 和新型四齿钴(II)-席夫碱配合物。[6]
四水合乙酸钴(II)可用作钴纳米颗粒[7]和氧化钴薄膜合成中的钴源。其也可用于制备钴(II)-氨基苯基四唑酸酯配位聚合物[5] 以及具有混合的μ-乙酰基和μ-吡唑配体的三钴复合物。[8] 乙酸钴(II)四水合物可提高使用过氧化氢将1,4-二氢吡啶氧化为相应的吡啶衍生物的反应速率。[9]

Questions

1–2 of 2 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
