一般說明

三氟化硼(BF3)是一种路易斯酸;它是由酸生成酯类的一种非常有用的试剂。三氟化硼可作为 14% 的甲醇溶液在市场上买到,用于形成酯衍生物。它催化在水浴中进行的反应非常迅速,可以在几分钟内完成。[1]三氟化硼催化植物油酯交换是最常用的方法之一。对于植物油的酯交换,BF3 用于甲醇中(15 至 20% w/v)。[2]

應用

更多信息请参见产品信息
基于缩酮与过氧化氢在无水乙醚中的溶液的反应,三氟化硼 - 甲醇溶液可用于催化用于合成二氢过氧化物及其衍生物的方法。[3]它还可以用于快速制备用于气相色谱分析的脂肪酸酯,因为它在约 2 分钟内将脂肪酸转化为它们各自的甲酯。[4]
适用于羟基脂肪酸的衍生化。

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
