一般說明

丙二酸二乙酯是丙二酸的二乙酯形式。它广泛用于将丙二酸官能团引入分子的多功能合成砌块。[1]使用氯化镁和三乙胺对丙二酸二乙酯进行酰化已有报道。[2]通过K2CO3催化的丙二酸二乙酯与各种取代形式的1,2-联烯酮的1,4加成反应,生成多官能化的β,γ-不饱和烯酮。[3]

應用

利用沸石催化剂(通过在Nax和CSNax沸石上接枝氨基得到),使用丙二酸二乙酯对微反应器中的Knoevenagel缩合反应进行研究。[4]它可以通过碱催化与苯甲醛进行Knoevenagel缩合,以合成二亚苄基丙二酸酯。[5]它可用于合成α-芳基丙二酸酯。[6]

The K2CO3 (10 mol %)-catalyzed 1,4-addition reaction of diethyl malonate with various substituted 1,2-allenic ketones leading to polyfunctionalized beta,gamma-unsaturated enones 3 or 4 was studied. With 3-unsubstituted 1-substituted-1,2-allenyl ketones, the highly selective formation of beta,gamma-unsaturated enones 4 was observed; with

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
