一般說明

http://www.sigmaaldrich.com/dam/sigma-aldrich/docs/Aldrich/Acta/al_acta_37_1.pdf
三己基十四烷基膦酸二(2,4,4-三甲基戊基)酯是一种膦基离子液体。[1]它可以通过在碱存在下,使三己基(十四烷基)-氯化膦与二(2,4,4-三甲基戊基)次磷酸反应来制备。[2]

應用

它可以作为萃取剂用于液体燃料中二苯并噻吩的萃取脱硫。[3]

特點和優勢

膦基离子液体具有有趣的属性,例如:
  • 室温液体或 T <100°C 时熔化
  • 高热稳定性
  • 与水不混溶的
  • 溶于有机溶剂(然而,当系统中加入过量的水时,会形成三种液相)
  • 碱性条件下稳定

其他說明

一种用作极性溶剂的次磷酸磷鎓盐

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

  3. Trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl)phosphinate is this compound applicable in metal separation (solvent extraction). I am interested in separation of transition metals and lanthanides.

    1 answer
    1. This product, as well as other phosphonium-based ionic liquids offered, have not been tested for suitability in the separation of lanthanides. Please see the links below for information that may be helpful.
