一般描述

二甲基二氯硅烷(DMDCS)是四面体构型的有机硅化合物。可用作硅烷偶联剂，用于合成亲水和疏水性二氧化硅纳米颗粒。还用于合成聚硅烷，作为碳化硅前体。[1][2]

应用


  • 从二氯硅烷、三氯硅烷和四氯硅烷合成甲基一氯硅烷的一般和选择性——讨论了一种合成甲基一氯硅烷的方法，显示了在化学合成中的各种应用潜力（Y Naganawa et al., 2020）。

  • 二氯甲基硅烷脱氯后，甲基硅烷聚合成聚甲基硅烷或聚碳硅烷。-研究甲基硅烷的聚合，为从二氯甲基硅烷生产聚甲基硅烷或聚碳硅烷提供启示（Y Tian et al., 2016）。

  • 利用二氯甲基硅烷单体合成低粘度聚甲基氢硅氧烷——重点关注通过二氯甲基硅烷的水解缩聚生产低粘度聚甲基氢硅氧烷，这对各种工业应用具有重要意义（VF Arini et al., 2022）。

Questions

1–2 of 2 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
