Descripción general

El alcohol etílico puro es un etanol no desnaturalizado de graduación 200. El etanol, un alcohol primario, es una materia prima importante para la síntesis de varios compuestos. Puede sintetizarse o bien a partir de melazas mediante fermentación o mediante hidratación del etileno. Actúa como una fuente de hidrógeno y como medio de reacción durante la hidrogenación de compuestos carbonilo por transferencia en presencia de hidróxido de sodio.[1] Se ha estudiado el efecto de la fumigación de etanol o agua en el rendimiento de los motores diésel.[2] El disolvente de calidad espectrofotométrica es de gran pureza con baja absorción UV.
Los precios incluyen los impuestos federales.
Nos hemos comprometido a proporcionarle los productos alternativos más sostenibles, que se adhieran a uno o más de los 12 principios de la química sostenible. El etanol es un disolvente verde medioambientalmente preferible y, por lo tanto, se alinea con los "Disolventes y auxiliares más seguros" y el "Uso de materias primas renovables". 

Aplicación

Se ha utilizado alcohol etílico (etanol) puro para preparar:
  • Disolución de etanol para la síntesis de Ga-68 DOTATATE [DOTA-(Tyr3)-octreotato (donde DOTA = ácido 1,4,7,10-tetraazaciclo- dodecano-1,4,7,10-tetraacético) mediante un sistema de síntesis automatizado.
  • Disolución de reserva de ácido aristolóquico para análisis espectrofotométrico.[3]
  • Partículas de nanocáscaras (o nanoshells) de núcleo de sílice mediante un método Stöber modificado.[4]
  • Disolución de polivinilpirrolidona (PVP) en combinación con agua para la síntesis de fibras ultrafinas de PVP mediante el método de soplo (de aire) de la disolución.[5]

Questions

1–10 of 10 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 expiration date of Ethyl Alcohol SHBQ4896/459828-1L?

    1 answer

    1. This product is not assigned an expiration date or recommended retest date. Products with no expiration date or recommended retest date should be routinely inspected by customers to ensure they perform as expected. These products are also subject to a one year warranty from the date of shipment. For more information you may access the "Product Dating Information" document under "ADDITIONAL USEFUL DOCUMENTS ABOUT OUR PRODUCTS" at the bottom of the Quality Services page with this link: https://www.sigmaaldrich.com/life-science/quality-and-regulatory-management/quality-services.

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

    1 answer

    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.

  5. What are the options for drying solvents?

    1 answer

    1. 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.

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

    1 answer

    1. Email us at [email protected] or visit Sigma-Aldrich Fine Chemicals for development and manufacturing-scale inquiries: [email protected]

  7. What is 190 proof and 200 proof ethanol?

    1 answer

    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.

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

    1 answer

    1. 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.

      Helpful?

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

    1 answer

    1. 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.

      Helpful?

  10. What is the Department of Transportation shipping information for this product?

    1 answer

    1. Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.
