一般描述

丁醇是一种工业溶剂,可从石油原料或生物质发酵中得到。它具有能量高、蒸汽压低、与汽油结合性能好等特点。[1]以1-丁醇为原料,在 γ-氧化铝、沸石、龙涎香离子交换树脂的存在下,在固定床流化反应器中脱水合成了二n-丁基醚(DBE)。[2]已经计算得到它的热物理性质。[3]已有研究在不同条件下,油菜籽和麻风树油在酸催化剂作用下,经1-丁醇酯交换生成脂肪酸丁酯(FABE)。[4]

应用

南极洲假丝酵母 脂肪酶和正己烷溶剂存在下,1-丁醇可用于乳酸的酯化。[5]

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.

  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. Bonjour, Quelle est la date limite de consommation ? Il y a t'il un péremption pour ce produit ? Qu'elle est sa durée de vie ? Merci d'avance pour votre retour

    1 answer
    1. This product does not contain 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.
