General description

El éter de dietilo (DEE) es un compuesto orgánico inflamable y muy volátil comúnmente utilizado como disolvente en síntesis orgánica. El DEE puede generar peróxidos orgánicos cuando se almacena durante mucho tiempo, lo que puede evitarse agregando hidroxitolueno butilado (BHT) como estabilizador. El BHT secuestra los radicales libres requeridos para la formación de peróxido.

Application

El disolvente de grado ACS éter de dietilo cumple o excede los elevados estándares de la American Chemical Society (ACS). Es ideal para la mayoría de las necesidades experimentales y ofrece resultados replicables y publicables.
El disolvente de grado ACS éter de dietilo se utiliza en:      
  • Síntesis química habitual      
  • Purificación y secado      
  • Limpieza crucial del material de laboratorio

Questions

1–2 of 2 Questions  

  1. 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

  2. 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
