一般描述

二氯甲烷是一种氯化有机溶剂,易随时间降解。添加戊烯作为稳定剂可抑制其降解。
对二氯甲烷作为二吡啶-氧化铬(VI)的溶剂介质进行了测试。据报道,溶解度为12.5 g/100 ml。[1]研究了活性炭载体上TiO2负载量对二氯甲烷光分解的作用。[2]

应用

二氯甲烷可用于气相色谱法(GC)定量检测草食性动物(舞毒蛾)诱导的蓝莓挥发物。[3]
二氯甲烷可用作使用二吡啶-氧化铬(VI)氧化伯醇和仲醇的溶剂。[1]悬浮于DCM中的高氯酸锂是醛与甲硅烷基乙烯酮缩醛进行Mukaiyama醇醛缩合反应的有效介质。[4]DCM也可用作通过锂-溴交换反应由2,6-二溴吡啶合成2-溴-6-硫代吡啶的溶剂。[5]

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
