一般說明

二碘甲烷是一种溶剂，可用作形成金属卤化物的卤键供体。[1]

二碘甲烷(CH2I2)是一种含碘的有机化合物。 通过在310nm处光引发，它在乙腈中的分解已有研究。[2]通过飞秒泵浦探针光谱和从头分子动力学模拟对CH2I2的光分解研究表明，该过程可产生二碘甲烷的异构体(CH2I-I)作为热光产物。[2][3]在大气中，它可在臭氧存在下进行光解，并产生碘氧化物(IO)，该过程会导致形成气溶胶。其真空紫外(VUV)光吸收光谱已有报道。[4]

應用

二碘甲烷可用作接触角测量中的探针溶剂，以分析聚合物表面的亲水性。[5]
二碘甲烷已被用作探针液，用于评价儿茶酚胺涂覆的纤维表面的表面能的极性和分散组分。[6]它可用于制备环丙基酮、酯和酰胺。[7]

Photodissociation of diiodomethane (CH2I2) in acetonitrile solution has been studied with ab initio molecular dynamics simulations, which show how the iso-diiodomethane photoproduct (CH2I-I) can be formed. The first excited state, described by the "restricted open-shell Kohn-Sham" density functional method, is

Questions

1–3 of 3 Questions  

  1. 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

  2. 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

  3. What is the shelf life of this material with the copper stabilizer?

    1 answer

    1. This product is not assigned an expiration date or recommended retest date. Products with no expiration date or recommended retest date should be routinely inspected by customers to ensure they perform as expected. These products are also subject to a one year warranty from the date of shipment. For more information you may access the "Product Dating Information" document under "ADDITIONAL USEFUL DOCUMENTS ABOUT OUR PRODUCTS" at the bottom of the Quality Services page with this link: https://www.sigmaaldrich.com/life-science/quality-and-regulatory-management/quality-services.
