Chemische Eigenschaften
CLEAR COLOURLESS LIQUID
Verwenden
Trimethylene oxide useful for the synthesis of 3-substituted propanols by reaction with Grignards or organolithiums in the presence of CuBr.
Definition
ChEBI: A saturated organic heteromonocyclic parent that is a four-membered ring comprising of three carbon atoms and an oxygen atom.
Allgemeine Beschreibung
Clear, colorless liquid with an agreeable aromatic odor.
Air & Water Reaktionen
Highly flammable. Water soluble.
Reaktivität anzeigen
TRIMETHYLENE OXIDE reacts with Grignard reagents and organolithium compounds. TRIMETHYLENE OXIDE is also incompatible with oxidizing agents and strong acids. . An explosion occurred when propylene oxide was added to epoxy resin. Polymerization was catalyzed by amine accelerator in the resin [Bretherick 1995]. Propylene oxide and sodium hydroxide base-catalyzed the polymerization of the former, causing ignition and explosion of a drum of the crude product. [Combust Sci. Technol., 1983].
Brandgefahr
TRIMETHYLENE OXIDE is flammable.
Sicherheitsprofil
Moderately toxic by subcutaneous route. May be narcotic in high concentrations. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes
Synthese
Trimethylene oxide, also known as 1,3-epoxypropane, can be obtained by ring-closing 3-bromo-1-propanol.
läuterung methode
Distil oxetane twice from sodium metal and then fractionate it through a small column at atmospheric pressure, b 47.0-47.2o. It can also be purified by preparative gas chromatography using a 2m silica gel column. Alternatively, add KOH pellets (50g for 100g of oxetane) and distil it through an efficient column or a column packed with 1/4in Berl Saddles with the main portion boiling at 45-50o being collected and redistilled over fused KOH.
