| | Tetrahydropyran Usage And Synthesis |
| Chemical Properties | colorless to light yellow liquid | | Uses | It is is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and dyestuff. They are also used as important solvents, as chemical intermediate and as monomer for ring-opening polymerization. | | 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| ChEBI: A saturated organic heteromonocyclic parent that is cyclohexane in which one of the carbon atoms has been replaced by an oxygen atom.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.
