OriginIsopropyl acetate is synthesized from isopropyl alcohol and acetic acid, both petrochemical-derived compounds. It is produced through esterification, where isopropyl alcohol reacts with acetic acid in the presence of a catalyst.
Isopropyl acetate appears as a clear colorless liquid. Flash point 40 °F. Vapors are heavier than air. Contact with the material may irritate skin, eyes or mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Used as a solvent.
