一般描述

过硫酸钠，又称过氧二硫酸钠，是一种无机化合物，是一种水溶性强氧化剂，稳定性好，易于处理。它通常用作有机合成反应的氧化剂，如过渡金属催化反应或无金属反应。此外，它还被用作聚合引发剂和通过热活化分解合成硫酸盐自由基阴离子。 [1]

应用

过硫酸钠可用作氧化剂：
  • 2-炔基苯并腈与芳基亚磺酸钠的自由基环化级联反应，以合成磺化茚酮。
  • 通过二氧化硅负载的氯化铝催化 Baeyer-Villiger 氧化将环和无环酮转化为内酯或酯。
还可用作苯乙烯聚合的引发剂，以合成聚苯乙烯。

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
