一般描述

四氢呋喃(THF)是一种杂环化合物(环醚)。无色、低粘度,在多种溶剂中具有优越的溶解性。广泛用作有机合成溶剂,常用于含有机金属化合物和Grignard试剂的反应。由于长期存放容易产生过氧化物,THF中常添加丁羟甲苯(BHT)稳定剂,BHT能去除形成过氧化物所需的自由基。

应用

四氢呋喃(THF)可作为溶剂用于以下过程:
  • 有机合成
a) Grignard
b) 有机金属化合物
c) Reformatsky
D) 锂化
e) 氢化物还原
f) 金属催化偶联(Heck, Stile, Suzuki)
g) 路易斯介导反应
  • 结晶
  • 聚合。如对乙酰氧基苯乙烯的RAFT(可逆加成断裂链转移)聚合。
  • 涂料
  • 作为O-供体配体,形成配位络合物
  • 作为高效液相色谱的流动相溶剂

特点和优势

ACS溶剂品质满足或超过美国化学学会(ACS)的高标准,每种化合物都具有特定的检验规格。根据美国化学学会标准,ACS试剂级代表物质纯度足够用于大多数化学分析或反应。

Questions

1–2 of 2 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
