一般說明

硝酸银,又称硝酸银(I)盐,是一种无臭、无色或白色的多用途无机化合物,因其具有硬化、脱水和硬化的特性而被广泛用作氧化剂和烧灼剂。它通常用作有机硅烷水解氧化的催化剂,导致生产高产氢率和有机硅醇。 [1]

應用

硝酸银可用作催化剂:      
  • 用于苯衍生物的 Friedel-Crafts 酰化,以合成相应的酮类。[2]     
  • 有机硅烷的水解氧化,以产生氢。[3]

它可用于制备一些负载酸催化剂,以进行各种有机转化。例如:      
  • 基于 AgNO3–SiO2 的催化剂用于进行螺环化脱芳反应。[4]      
  • 聚苯胺-AgNO3-PTSA(对甲苯磺酸)催化剂用于通过芳香醛、芳香胺和环己酮的三组分曼尼希反应合成抗-β-氨基酮。[5]

AgNO3 也用作前体盐来合成银纳米颗粒。[6]

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
