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. The impact of ethanol/water fumigation on the performance of diesel engines has been studied. ACS grade solvent can be used for processes requiring strict quality conditions such as analytical testing.

Application

Pure ethyl alcohol (Ethanol) has been used in the following processes:
  • Preparation of AMBF3 (ammoniomethyltrifluoroborate)-conjugated biomolecules.
  • As an absorbing liquid for the determination of Grüneisen parameter by photoacoustic measurement in an integrating sphere system.
  • Solid-phase microextraction (SPME) on-fiber derivatization analysis of resveratrol extracted from red wine.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Who do I contact about larger solvent volume needs?

    Email us at labessentials@sial.com or visit Sigma-Aldrich Fine Chemicals for development and manufacturing-scale inquiries: safcglobal@sial.com

  4. How do I know what packaging options are available for a solvent?

    The Solvent Center gives you the ability to review all the specifications associated with our solvent packaging. This includes physical dimensions, closure types, dispensing methods, UN/DOT Rating as well as solvent compatibility. Visit the Solvent Center.

  5. Who do I contact if I need a solvent blend, which you do not carry?

    Email us at labessentials@sial.com. For a complete listing of all our Solvent blends, visit the Solvent Center

  6. The dispensing of solvents provides some challenges due to the number of container options available. What dispensing options are available for each container?

    The Sigma-Aldrich Solvent Center provides numerous dispensing options for each container type. For a complete listing of all our dispensing options, visit the Solvent Center.

  7. Which solvent grade should I be using for my application?

    Sigma-Aldrich Solvent Applications Table gives a guideline to common applications and the appropriate solvent grades.  Visit: Solvents

  8. What are the options for drying solvents? 

    Sigma-Aldrich offers a full range of high-purity solvents with extremely low water levels specifically manufactured for moisture sensitive Organic and Biotech applications.  Sigma-Aldrich also carries various drying agents such as molecular sieves, which are typically compatible with organic solvents.

  9. What apparatus do you recommend for HPLC solvent filtration?

    The Sigma-Aldrich Vacuum Filtration Assembly gives you all the components you need including: funnel top, fritted glass funnel support, filtration flask, aluminum clamp, and silicone stopper.  The Acrodisc Syringe Filters offer high quality filtration for analytical samples, certified for HPLC to ensure low extractable and available in a broad range of membranes to meet sample compatibility requirements.

  10. Can you recommend a Solvent Extractor for organics from aqueous solution?

    Solvent extractors are often used for the quantitative extraction of organics from aqueous solutions and separations in immunoassays. The MIXXOR system has been applied successfully in many laboratory solvent extraction operations and is ideal for the rapid screening of alternative solvents for specific extraction problems.
