일반 설명

Acetic anhydride is a carboxylic acid anhydride commonly used as an acetylating agent for amines and alcohols.[1]
Acetic anhydride participates in the Friedel-Craft′s intramolecular cyclization reaction of cyclopropyl ketones to afford the tetralones.[2] It has been reported to promote the Knoevenagel condensation of various aldehydes and activated methylene compounds.[3]

애플리케이션

Acetic anhydride may be used as a reactant to synthesize:
  • 3-acetoxybenzoic acid by reacting with 3-hydroxybenzoic acid[4]
  • 6-dimethylamino-2,3-naphthalenedicarboxylic anhydride, a precursor to prepare 6-dimethylaminonaphthalimide[5]

Acetic anhydride was used in the following studies:
  • Lipozyme TL IM (commercial immobilized lipase from Thermomyces lanuginosus) catalyzed acetylation of essential clove oil.[6]
  • As acetyl donor to investigate the lipase catalyzed acetylation of nanofibrillated cellulose (NFC).[7]
  • Synthesis of N-substituted pyrazolines.[8]
  • Acetylation of Barnyardgrass (Echinochloa crus-galli) starch.[9]

A new series of chalcones 5a-f were synthesized from caffeine-based aldehyde 3 and substituted acetophenones 4a-f. Treatment of compounds 5a-f with hydrazine hydrate led to pyrazolines 6a-f, and their subsequent reaction with acetic anhydride or formic acid afforded the corresponding

The pyrazole analogues of podophyllotoxin were synthesized by the chalcone route. This route attracts the attention because of its simple operating conditions and easy availability ofthe chemicals. Initially, benzylide-neacetophenones (chalcones) were prepared in high yields by Claisen-Schmidt reaction of acetophenones

The combination of a catalytic amount of InCl3 and acetic anhydride remarkably promotes the Knoevenagel condensation of a variety of aldehydes and activated methylene compounds. This catalytic system accommodates aromatic aldehydes containing a variety of electron-donating and -withdrawing groups, heteroaromatic

질문

1–2 / 2 질문  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 답변

    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 답변

    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
