Descripción general

1,3-dioxolane is a heterocyclic acetal that is commonly used as a green solvent in formulations and production processes. It is also used as a reactant in organic synthesis. Long-term storage of 1,3-dioxolane forms organic peroxides. This process can be suppressed by adding butylated hydroxytoluene (BHT) as a stabilizer. BHT removes the free radicals required for peroxide formation.

Aplicación

1,3-dioxolane can be used as a solvent:      
  • For the extraction of biodegradable poly(3-hydroxybutyrate) (PHB) from biomass.     
  • To produce stable dispersions of multiwalled carbon nanotubes (MWCNTs) for the synthesis of modified glassy carbon electrodes.
  • To synthesize copolymers (polyoxymethylene) by cationic copolymerization of 1,3,5-trioxane in the presence of maghnite-H+ as a catalyst.

It is also used as a reactant to prepare quasi-solid-state poly(1,3-dioxolane) electrolyte by Sc(OTf)3 catalyzed ring-opening polymerization reactions.

The gold-catalyzed preparation of 2-azetidinone-fused oxacycles was accomplished from β-lactam-linked enynes through heterocyclization reaction taking advantage of the acetonide pendant group. While the synthesis of fused tetrahydrofuran-β-lactams from 1,3-enynes could be considered as an unusual metal-catalyzed cyclization of enynols, α-alkoxy

Low catalyst loading of a cationic oxorhenium(V) oxazoline complex, [2-(2'-hydroxyphenyl)-2-oxazolinato(-2)]oxorhenium(v), condenses diols and aldehydes to give 1,3-dioxolanes in excellent yields under neat conditions and reasonably mild temperatures. The reaction is applicable to biomass-derived furfural and glycerol. The resulting cyclic acetals

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
