一般描述

乙酸丁酯是乙酸的丁酯。它以四种异构体形式存在:乙酸丁酯、-乙酸丁酯、 乙酸丁酯和 -乙酸丁酯。本品为无色的宜人嗅液。[1]
乙酸丁酯(BA, n -乙酸丁酯)是一种酯类物质,通常用作化妆品和制药行业的有机溶剂,以及食品工业中的调味剂。[2][3] 报道的合成方法之一是可膨胀石墨 (EG) 催化乙酸与丁醇的酯化反应。[2]采用 TiO 2 、Pt/TiO 2 和 WO 3 /TiO 2 催化剂,研究了气相光催化分解乙酸丁酯的反应。[4]BA 是一种可能的生物燃料添加剂。[5]

应用

醋酸丁酯可用于从土壤提取物中提取铝-羟基喹啉络合物,用于分光光度法和荧光法测定铝。[6]也可用于从矿石中提取痕量金,然后用火焰原子吸收光谱法测定。[7]
醋酸丁酯已被用于制备用于免疫组织化学 (IHC) 和免疫荧光 (IF) 染色的睾丸组织和细胞培养物。[8]

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
