Descripción general

Removal of styrene from textile dyeing wastewater treatment plants (TDWTPs) has been investigated.[1] Catalytic potential of the Co-SBA-15 for the oxidation of styrene with hydrogen peroxide has been investigated.[2] Screening of asymmetric epoxidation of styrene by gas chromatography-mass spectrometry (GC-MS) with selected ion monitoring (SIM) has been reported.[3] The homogeneous atom transfer radical polymerization (ATRP) of styrene by employing solubilizing 4,4′-dialkyl substituted 2,2′-bipyridines affords well-defined polymers.[2] The Heck reaction of chlorobenzene and substituted chlorobenzenes with styrene in water using catalytic palladium on carbon affords 1,2-diphenylethane.[4]

Aplicación

Styrene has been used as a test styrene sample in a study involving the effect of reversible addition-fragmentation chain transfer (RAFT) controllers on its RAFT polymerization in supercritical carbon dioxide in the presence of poly(styrene-block-dimethylsiloxane) (PSDMS) as a stabilizer.[5]
Styrene was used in the preparation of well-defined homopolymers, diblock copolymers and triblock copolymers of tert-butyl acrylate, methyl acrylate and styrene.[6]

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
