Allgemeine Beschreibung

Sodium hydroxide also known as caustic soda is a water soluble base with a wide range of industrial applications.

Anwendung

Sodium hydroxide may be used in the following processes:
  • Titration methods.[1]
  • Dissolution testing.[2]
  • As a base for adjusting pH.[3][4]
  • As a reducing agent to initiate the synthesis of resin-supported silver nanoparticles.[5]
  • As an alternative to sodium hydride in the carbon-11 methylation reaction in the synthesis of [11C]diprenorphine. [6]
  • Preparation of bead cellulose loaded with iron oxyhydroxide (BCF).[7]
  • Synthesis of polyethyleneimine-sodium xanthogenate (PEX).[8]
  • Pretreatment of thickened waste activated sludge during anaerobic digestion.[9]
  • Struvite precipitation recycling technology.[10]
  • Production of sewage-sludge-based activated carbons.[11]
  • Preparation of β-cyclodextrin (β-CD)/cellulose hydrogels.[12]
  • Prion inactivation during industrial decontamination procedure.[13]
  • Pretreatment of sugarcane bagasse for the sugar recovery.[14]
  • In the Impinger to remove acidic gases.[15]

Microemulsions are often used in the synthesis of nanoparticles in solution. In this work, we put forward the concept of a "hard microemulsion", which is based on the differential partitioning of water and ethanol solvent molecules inside functional polymer matrices.

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.
      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

  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
