一般描述

丙酰氯是一种重要化学中间体，用于合成各种丙酸衍生物。。

应用

丙酰氯可用作以下反应的酰化剂：
  • 在氯化铟(InCl3)浸染的介孔Si-MCM-41催化剂作用下，将苯甲醚转化为4-间甲氧基苯丙酮以及2-甲氧基萘转化为1-丙氧基-2-甲氧基萘。[1]

此外，还可用于：
  • 在存在硫酰氯和过氧化物的条件下氯化，形成α-氯丙酰氯和β-氯丙酰氯。[2]
  • 与（羟丙基）纤维素反应生成丙酸酯、[(丙酰氧基)丙基]纤维素。[3]

Questions

1–3 of 3 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
