Hazard Information | Back Directory | [General Description]
Clear, colorless liquid with an agreeable aromatic odor. | [Reactivity Profile]
1,3-PROPYLENE OXIDE(503-30-0) reacts with Grignard reagents and organolithium compounds. 1,3-PROPYLENE OXIDE(503-30-0) 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]. | [Air & Water Reactions]
Highly flammable. Water soluble. | [Fire Hazard]
This chemical is flammable. | [Chemical Properties]
CLEAR COLOURLESS LIQUID | [Uses]
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. | [Purification Methods]
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.
