Descripción general

Ethanol (denatured), a primary alcohol, is a constituent of hairspray, disinfectants and cosmetics.[1] It can be synthesized either from molasses by fermentation or by hydration of ethylene.[2] It is made non-consumable by the addition of denaturants.[1]
The product is denatured ethyl alcohol and it contains following as denaturant:
  • 1% ethyl acetate
  • 1% hydrocarbons
  • 1% methyl isobutyl ketone
  • 5% methanol
Ethanol, a primary alcohol is an important raw material for the synthesis of various compounds. It can be synthesized either from molasses by fermentation or by hydration of ethylene. It acts as a hydrogen source and reaction medium during the transfer hydrogenation of carbonyl compounds in the presence of sodium hydroxide.[3] The impact of ethanol/water fumigation on the performance of diesel engines has been studied.[4] Denatured alcohol is also referred to as industrial methylated spirit.[5]

Aplicación

Ethyl alcohol (denatured ethanol) may be used to compose the Nital etchant for use in microstructural analysis.[6]

Questions

1–3 of 3 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.

  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
