  • Process for production and purification of triacetin
    Patent number: 5777157
    Abstract: A method for producing and purifying triacetin. The method includes an initial separation of triacetin from a crude composition of triacetin and impurities. The separated triacetin is then contacted with an aqueous solution containing an oxidant, and results in an odorless and colorless purified triacetin.
