1,3-Dioxolane (CAS: 646-06-0)
Common Names: Dioxolane, Ethylene glycol methylene ether, Formaldehyde ethylene acetal
A polar aprotic cyclic diether with active solvency 1,3-Dioxolane is a highly polar aprotic (no hydroxyl functionality) solvent, having low toxicity. The moderate boiling point allows for easy separation and recovery from reaction mixtures. Novolyte offers the highest purity (99.9%, (99.95% typical), low peroxide (5ppm max), and low moisture (150ppm max).
