Descripción general

Heterogeneous ozonolysis of naphthalene adsorbed on XAD-4 resin has been studied using annular denuder technique[1].

Naphthalene is widely used to synthesize naphthylamines,sulfonic acid,synthetic resins,anthranilic and phthalic acids.[2]

Aplicación

Naphthalene was used in liquid-phase exfoliation of graphite in organic solvents for the production of graphene sheets[3]. It was used in preparation of carbon-coated Si70Sn30 nanoparticles[4]. It was used as fluorescent probe to study the aggregation behavior of sodium cholate[5].

We report a facile method for the production of graphene sheets through liquid-phase exfoliation of graphite in organic solvents with addition of naphthalene. The production yield of graphene is significantly increased with the addition of naphthalene in most solvents tested

Preguntas

1–2 de 2 Preguntas  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 respuesta
    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 respuesta
    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
