Descripción general

El perclorato de sodio monohidratado (NaClO4· H2O) es una sal de sodio hidratada. Se ha comunicado que sus cristales exhiben sistema cristalino monoclínico con grupo espacial C2/c. Es un oxidante fuerte.

Aplicación

El perclorato de sodio monohidratado puede:
  • Utilizarse como electrólito de soporte en la preparación de la película de polipirrol (PPy).
  • Doparse con polímero huésped NaCMC (carboximetilcelulosa sódica) para preparar la película electrolítica (NaCMC-NaClO4 H2O) que se utiliza en la pila electroquímica.
  • Se utiliza como oxidante para eliminar el color de las aguas residuales textiles.

Questions

1–2 of 2 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.

  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
