一般描述

苯胺是一种芳香胺。它是一种重要的工业中间体，广泛用于制备染料、橡胶、树脂和聚合物。[1]已经报道了苯胺及其氘化形式（苯胺-NHD和苯胺-ND2）的完全振动分配。1据报道，p-氨基二苯胺（ADPA）是苯胺电聚合过程中的主要中间体。[2]据报道，其粘度在30℃为3.1457cp。[3]采用功能化等离激元Au/TiO2光催化剂和Ag助催化剂对硝基苯向苯胺进行定量转化。[4]在Cu、Ni、Pt、Pd和Au（催化剂）存在下，硝基苯发生氢化制备苯胺。也可以通过在WO3-Ag杂化纳米线存在下光催化还原硝基苯来制备。[1]

应用

苯胺可用于制备偶氮苯。[5]

生化/生理作用

苯胺的急性毒性涉及其在体内活化为4-羟基苯胺和与血红蛋白形成加合物。 在红细胞中，这与铁的释放和高铁血红蛋白的积累以及溶血性贫血和脾脏炎症的发展有关。长期给药时，在脾脏中常可观察到肿瘤形成。

物理属性

材料在储存期间颜色变暗，成为红棕色，但纯度不会受到影响。

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.
