Descrição geral

N,N-Dimethylacetamide (DMAc) is a water-miscible organic solvent used in the synthesis of styrene′s, vinyl resins, linear polyesters, acrylic fibers, plastics, pesticides, and synthetic leather. Additionally, it is utilized in the production of adhesives, films, and paint. It participates in dehydrogenation, dehydration, halogenation, deprotonation reactions and reductive carbonylation of transition metals. It can also act as catalysts, promoters, halogen/alkoxy or hydroxyl/halogen exchange mediators, reducing agents, and sources of the base.

Aplicação

N,N-Dimethylacetamide can be used as a solvent in the synthesis of:
  • Cellulose-HA (hydroxyapatite) nanocomposites using microcrystalline cellulose, CaCl2, and NaH2PO4.
  • 5-hydroxymethylfurfural (HMF) from various carbohydrates and natural biopolymer lignocellulose in the presence of LiCl. 

It can also be used:
  • In the Pd-catalyzed regioselective synthesis of ketones from olefins using molecular oxygen.
  • As a solvent as well as a methylene source in the regioselective linkage of two imidazo[1,2-a] pyridines using Cu(OAc)2 catalyst.

Características e benefícios

N,N-Dimethylacetamide has
  • High dissolution power of various substrate.
  • High capacity to solvate anions.

An amphiphilic triblock co-polymer of poly(vinyl pyrrolidone)-b-poly(methyl methacrylate)-b-poly(vinyl pyrrolidone) (PVP-b-PMMA-b-PVP) was synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization. The block co-polymer can be directly blended with polyethersulfone (PES) using dimethylacetamide (DMAC) as the solvent to prepare flat sheet and

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
