Applicazioni

Lithium tetrafluoroborate (LiBF₄) is used as an electrolyte salt in lithium-ion batteries. It contributes to the overall ionic conductivity of the electrolyte and helps in achieving better battery performance. LiBF₄ is used as an electrolyte additive in supercapacitors to enhance their performance, particularly in terms of energy density and charge-discharge cycles. It can be used as a catalyst in various chemical reactions. Its properties can help improve the efficiency and selectivity of catalytic processes. In a study, it was reported that lithium tetrafluoroborate can serve as an efficient catalyst for the intermolecular aza-Michael addition of aromatic amines to electron-deficient alkenes. The suitability of this catalyst for intramolecular aza-Michael addition, resulting in the formation of 2-aryl-2,3-dihydroquinolin-4(1H)-ones, was also described. Lithium tetrafluoroborate is a mild Lewis acid for Diels-Alder reactions. It is used as a catalyst for mild and efficient aminolysis of oxiranes.[1][2][3][4]

Domande

1–2 di 2 domande  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 risposta

    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 risposta

    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
