Health  
Flammability   3 Liquids and solids (including finely divided suspended solids) that can be ignited under almost all ambient temperature conditions . Liquids having a flash point below 22.8 °C (73 °F) and having a boiling point at or above 37.8 °C (100 °F) or having a flash point between 22.8 and 37.8 °C (73 and 100 °F). (e.g. gasoline, acetone)
Instability   1 Normally stable, but can become unstable at elevated temperatures and pressures (e.g. propene)

Tetrahydropyran Chemical Properties,Uses,Production

Chemical Properties

colorless to light yellow liquid

Definition

ChEBI: A saturated organic heteromonocyclic parent that is cyclohexane in which one of the carbon atoms has been replaced by an oxygen atom.

Purification Methods

Dry oxane with CaH2, then pass it through a column of silica gel to remove olefinic impurities and fractionally distil it. Free it from peroxides and moisture by refluxing with sodium, then distil it from LiAlH4. Alternatively, peroxides can be removed by treatment with aqueous ferrous sulfate and sodium bisulfate, followed by solid KOH, and fractional distillation from sodium. [Beilstein 17 H 12, 17 I 6, 17 II 18, 17 III/IV 51, 17/1 V 64.]
