oxein

Oxane, also known as tetrahydropyran (THP), is a heterocyclic organic compound with the chemical formula C5H10O. It is a six-membered ring containing five carbon atoms and one oxygen atom, saturated with hydrogen atoms. Oxane is a colorless liquid with a characteristic ether-like odor. It is miscible with water and many organic solvents.

Industrially, oxane is produced through the hydrogenation of dihydropyran or the cyclization of 1,5-pentanediol. It finds applications as a solvent, particularly for polymers and resins, due to its good solvency properties and relatively low toxicity. It is also used as an intermediate in the synthesis of various organic chemicals, including pharmaceuticals and fragrances.

Oxane can undergo various chemical reactions characteristic of ethers, such as cleavage under strong acidic conditions. It is generally considered a stable compound under normal conditions. Its cyclic structure and the presence of an oxygen atom influence its reactivity and physical properties. Safety precautions should be observed when handling oxane, as it is flammable.
