Opis ogólny

Ethylene glycol is a colorless liquid[1], which may be obtained via hydration of ethylene oxide.[2]
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food.

Zastosowanie

Ethylene glycol has been used as a solvent in the synthesis of silver nanostructures, which serve as effective catalysts in the epoxidation reaction of ethylene.[3]
It may be used as an analytical standard for the determination of the analyte in biological samples by various chromatography techniques.[4][5][6][7]

Questions

1–4 of 4 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

  3. What is the molarity of ethylene glycol?

    1 answer
    1. Ethylene glycol is 17.93M.  This is calculated using the density (1.113 g/ml) and the molecular weight (62.07 g/mol).  If the product is less than 100% pure, correct for the purity.
