一般說明

环己酮(无色液体)是一种环酮。它是合成多种有机化合物的重要组成部分。大多数合成的环己酮可用作合成尼龙的中间体。[1]已报道的合成方法之一是通过钯催化的苯酚氢化过程来实现。[2]环己酮的氧化反应的动力学已在熔融二氧化硅喷射搅拌反应器中进行了研究。[3]有关Meerwein-Ponndorf-Verley对环己酮进行还原已有报道。[4]

應用

  • 在聚合物理化性能方面的应用:研究强调了环己酮在开发聚偏氟乙烯气凝胶中的作用,强调了其在操纵多晶结构以在先进应用中调整物理化学特性方面的作用(Suresh et al., 2024)。

文章

Baeyer-Villiger 氧化作用是氧化裂解與羰基相鄰的碳-碳鍵,將酮類轉換為酯類,環酮類轉換為內酯類。

The Baeyer-Villiger oxidation is the oxidative cleavage of a carbon-carbon bond adjacent to a carbonyl, which converts the ketones to esters and the cyclic ketones to lactones.

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.

  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
