一般描述

Sodium nitrate (chile salpeter) is a hygroscopic compound and soluble in water. It is primarily used as an oxidizing agent in organic synthesis. Additionally, sodium nitrate is used in the manufacture of glass and charcoal briquettes, and the synthesis of potassium compounds.

应用

Sodium nitrate is used:
  • To modify hydroxyapatite to prepare heterogeneous catalyst (sodium nitrate/hydroxyapatite) for Claisen–Schmidt condensation process to synthesis of chalcones.
  • In the direct acetoxylation of arenes under an anhydrous environment of TFA (trifluoroacetic acid), acetic acid, and acetic anhydride.
  • As a redox mediator in the selective oxidation of aromatic alcohols in biphase electrolysis at ambient temperature.

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
