Description générale

Biodegradation of 2-ethylhexyl nitrate (2-EHN) by Mycobacterium austroafricanum IFP 2173 has been studied[1]. Biodegradation of 2-EHN was studied in biphasic liquid cultures using an inert non-aqueous phase liquid such as 2,2,4,4,6,8,8-heptamethylnonane as solvent[2].

Application

2-Ethylhexyl nitrate (2-EHN) is a major fuel additive, has been used to increase the cetane number of diesel[1].

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. 「第4類: 引火性液体、第三石油類、危険等級III、非水溶性液体」とありますが、分子構造から見ると第5類に分類されると思われます。また、記憶違いかもしれませんが、以前は第5類だったと記憶しています。何か、法令の改正などにより危険物の分類が変更されたのでしょうか。

    1 answer

    1. 2-Ethylhexyl nitrate has a flash point of 76.1°C (169°F). It is has a GHS (Globally Harmonized System) Flammability rating of 4, the least hazardous. While 2-Ethylhexyl nitrate is combustible, it is not as hazardous as, for example, Butane which has a GHS Flammability rating of 1; flammability is rated on a scale from 1-4 based on the flash point.

      Please download the current Safety Data Sheet (SDS) for Product 293784 for the most current information.
