Abstract
Methods for the generation of non-equilibrium solutions of peroxyacetic acid are disclosed. These methods comprise introducing triacetin and aqueous hydrogen peroxide to water, mixing, and then adding an aqueous source of an alkali metal or earth alkali metal hydroxide. Triacetin is converted rapidly and with a high conversion rate into peracetic acid. These methods produce solutions with a high level of peracetic acid.
Claims3
A hydrogen peroxide-acetyl precursor solution, comprising:
- a. aqueous hydrogen peroxide;
- b. triacetin;
- c. a trace amount of peracetic acid;
- and
- d. water.
