一般說明

已有对从纺织印染废水处理厂（TDWTP）中除去苯乙烯的研究。[1]Co-SBA-15在过氧化氢氧化苯乙烯过程中的催化潜力已有研究。[2]通过气相色谱-质谱（GC-MS）和选择离子监测（SIM）对苯乙烯的不对称环氧化进行筛选已有报道。[3]通过使用增溶的4,4′-二烷基取代的2,2′-联吡啶，可对苯乙烯进行均相原子转移自由基聚合(ATRP) ，从而生成成分确定的聚合物。[2]使用催化钯/碳，氯苯和取代的氯苯与苯乙烯在水中的Heck反应，可得到1,2-二苯基乙烷。[4]

應用

苯乙烯已用于制备成分确定的叔-丙烯酸丁酯、丙烯酸甲酯和苯乙烯的均聚物、二嵌段共聚物和三嵌段共聚物 。[5]
苯乙烯已被用作测试苯乙烯样品，该研究涉及在聚（苯乙烯-嵌段-二甲基硅氧烷）（PSDMS）作为稳定剂存在下，可逆加成-断裂链转移（RAFT）控制子对苯乙烯在超临界二氧化碳中的RAFT聚合作用的影响。[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
