摘要：Methods and compositions for the generation of a peroxyacetic acid sanitizer inproximity to the point-of-use are disclosed. These methods comprise introducing ahydrogen peroxide-acetyl precursor solution to water, mixing, and then adding anaqueous source of a alkali metal or earth alkali metal hydroxide. Triacetin is a preferredacetyl precursor and is converted rapidly and with a high conversion rate into peraceticacid. These methods produce solutions with a high level of peracetic acid. Methods forpreparing the hydrogen peroxide-acetyl precursor solution are also provided. Alsodisclosed are solid compositions comprising a liquid acetyl precursor, a water-solublesource of hydrogen peroxide, and a water-soluble source of alkalinity. The solidcomposition is a freely-flowable solid that is used as a bleaching agent and a stainremover for the treatment of articles such as fabrics, dentures, textile garments, andequipment used in the food and beverage industry.
