应用


  • 氧化反应：乙酸用于氧化反应，如二元醇在水中有氧氧化为乙酸。该工艺对于从可再生资源中生产乙酸具有重要意义，有助于实现可持续化工生产。最近的研究探索了催化剂在这些氧化反应中的使用，强调了乙酸在绿色化学应用中的潜力（Oberhauser, Results in Chemistry, 2023）。


特点和优势

认证：
此滴定溶液由我们获得DAkkS（Deutsche Akkreditierungsstelle，德国国家认证机构）DIN EN ISO/IEC 17025标准的滴定溶液物质的量浓度分析认可的校准实验室D-K-15185-01-00分析。认证证书请见www.sigmaaldrich.com/ISO17025.

分析说明

形态：液体
物质的量浓度 0.995 - 1.005 mol/L
测量不确定度± 0.003 mol/L
可溯源至NIST SRM

浓度通过容量滴定法在20°C测定。
此滴定溶液的物质的量浓度是使用ISO 17034标准的认证参考物质三羟甲基氨基甲烷基准试剂（货号1.02408）标定的，并可溯源至美国盖瑟斯堡国家标准技术研究所的一级标准参考物质(SRM)（NIST SRM 723 三羟甲基氨基甲烷），由我们的DIN EN ISO/IEC 17025标准认可的德国达姆施塔特默克校准实验室负责分析。不确定度表示为扩展的测量不确定度，覆盖因子k = 2，覆盖95％的置信度。

注意：滴定度是一种用于校正容量滴定溶液、滴定设备、温度和其他实验室条件变化的校正因子。为了获得正确的滴定结果，建议在打开新瓶后并在一定时间间隔内，立即使用实验室专用设备并在实验室特定条件下对滴定度进行确定。

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.

  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
