Application

Amberlyst® A26 hydroxide form is a strongly basic, macroreticular resin with quaternary ammonium functionality used to catalyze aldol condensation, also useful in aqueous and nonaqueous media to remove anionic transition metal complexes, mercaptans and acids from hydrocarbons and other nonpolar solvents. It was used to determine cadmium using flow injection atomic absorption spectrometry.[1] It was also used as packaging material for column chromatography assay.[2]
Strongly basic (type I) anion exchange resin used to remove transition metal complexes and mercaptans from hydrocarbons, remove acids from non-polar solvents, and deacidifying phenol-acetone solutions. Its porous structure makes it a good polymeric catalyst in non-aqueous and aqueous media; it has no pH limitations.

Features and Benefits

Inert in strong acids, concentrated aldalies, aliphatic and aromatic hydrocarbons, alcohols, ethers, and other common solvents.
Maximum operating temperature 60C.

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.
