Dioxolane is a heterocyclic acetal with the chemical formula (CH₂)₂O₂CH₂. It is related to tetrahydrofuran (THF) by replacement of the methylene group (CH₂) at the 2-position with an oxygen atom. The corresponding saturated 6-membered C₄O₂ rings are called dioxanes. The isomeric 1,2-dioxolane (wherein the two oxygen centers are adjacent) is a peroxide. 1,3-dioxolane is used as a solvent and as a comonomer in polyacetals.
