General description

El diclorometano es un disolvente orgánico clorado que es sensible a la degradación con el tiempo. Esto puede suprimirse añadiendo amileno como estabilizador.
El diclorometano se ha analizado como un medio disolvente para el óxido de dipiridina-cromo (VI). Se ha comunicado una solubilidad de 12,5 g/100 ml.[1] Se ha investigado el papel de la cantidad de carga de TiO2 en soporte de carbón activado empleado en la fotodescomposición del diclorometano.[2]

Application

El diclorometano puede utilizarse como disolvente para la oxidación de alcoholes primarios y secundarios utilizando dipiridina-óxido de cromo(VI).[1] El perclorato de litio suspendido en el MCD es un medio eficaz para las reacciones de adición de aldol de Mukaiyama de un aldehído con acetal de sililceteno.[3] El DCM también puede utilizarse como disolvente para la síntesis de 2-bromo-6-litiopiridina a partir de 2,6-dibromopiridina a través de una reacción de intercambio litio-bromo.[4]
El diclorometano se ha utilizado para cuantificar los volátiles de arándanos inducidos por herbívoros (polilla gitana) mediante cromatografía de gases (GC).[5]

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.
