General description

Dodecylbenzenesulfonic acid solution (DBSA) is a non-volatile and non-hygroscopic acid catalyst majorly used in the trans-esterification reaction. [1][2]

Application

DBSA can be used as a catalyst for the esterification of fatty acids (oleic acids) to produce biodiesel.[3] It can be used as a Bronsted acid catalyst for the green synthesis of quinoxaline derivatives which are used in a variety of pharmacological profiles.[1] It may be electrodeposited with polypyrrole(PPy) films on the aluminium alloy to protect against corrosion.[4] Water based nanofluids with enhanced thermal conductivity and specific heat capacity may be prepared by doping polyanaline (PANI) into DBSA.[5]
Dopant for conducting polymers strong acid catalyst for amino cross-linked coatings

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.
      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
