Descrizione generale

Price includes Federal Tax.
Pure ethyl alcohol is a non-denatured 200proof ethanol. 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.[1] The impact of ethanol/water fumigation on the performance of diesel engines has been studied.[2] Spectrophotometric grade solvent is of high purity with low UV absorption.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Ethanol is environmentally preferable green solvent and thus it aligns with "Safer Solvents and Auxiliaries" and "Use of Renewable Feedstocks". 

Applicazioni

Pure ethyl alcohol (Ethanol) has been used to prepare:
  • Ethanol solution for the synthesis of Ga-68 DOTATATE [DOTA-(Tyr3)-octreotate (where DOTA = 1,4,7,10-tetraazacyclo- dodecane-1,4,7,10-tetraacetic acid)] by an automated synthesis system.
  • Aristolochic acid stock solution for the spectrophotometric analysis.[3]
  • Core silica particles of nanoshells by a modified Stöber method.[4]
  • Polyvinylpyrrolidone (PVP) solution in combination with water for synthesizing PVP ultrafine fibers by solution (air-) blowing method.[5]

Domande

1–10 di 10 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

  8. How can I get help with the ATF paperwork for 190 and 200 proof ethanol?

    1 risposta
    1. Because these non-denatured ethanol products are federally regulated, an ATF permit is required to purchase 190 and 200 proof ethanol. Sigma-Aldrich takes the hassle out of this process for you! There is no ATF paperwork needed or records to be kept on your part. Sigma-Aldrich holds the permit, and immediately pays the federal excise tax. For more regulatory information regarding the tax on ethanol, visit the U.S. Department of Justice, Bureau of Alcohol, Tobacco, Firearms and Explosives.

  9. What is 190 proof and 200 proof ethanol?

    1 risposta
    1. All non-denatured ethanol products have a proof associated with the product description. The proof is a measure of the water content of the ethanol portion of the product. The proof is calculated as two times (2 x) the actual ethanol concentration by volume.
