General description

Boron trifluoride (BF3) is a Lewis acid; it is a very useful reagent for forming esters from acids. Boron trifluoride is commercially available as a 14% solution in methanol for forming esters derivatives. It catalysed reactions carried out in a water bath are very rapid and can be completed in a few minutes.[1] Boron-trifluoride-catalysed transesterification of vegetable oils is one of the most popular methods. For transesterification of vegetable oils, BF3 is used in methanol (15 to 20% w/v).[2]

Application

Learn more in the Product Information
Boron trifluoride-methanol solution may be used for catalysing a method, used for the synthesis of bishydroperoxides and their derivatives, based on a reaction of ketals with a solution of hydrogen peroxide in anhydrous ether.[3] It may also be used for the rapid preparation of fatty acid esters for gas chromatographic analysis, as it converts fatty acids to their respective methyl esters in about 2 minutes.[4]
Suitable for derivatization of hydroxy fatty acids.

Other Notes

Reagent for esterifying fatty acid for gas chromatographic analysis.
Reagent for methyl ester, O-acetyl.

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.
      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

  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
