With a total of 3 patents to her name, her work has had a substantial impact on the industry.

Latest Patents

One of her latest patents is titled "Improved process for recovery of purified terephthalic acid." This invention discloses a method for preparing purified terephthalic acid that contains 200 ppmw or less of p-toluic acid. The process involves filtering an aqueous slurry of purified terephthalic acid under specific conditions to create a filter cake. The remaining p-toluic acid is then displaced from the filter cake using water, followed by pressure flash evaporation to yield a crystalline terephthalic acid product. This purified terephthalic acid is essential for manufacturing polyesters used in clothing and related goods.

Another significant patent by Graziano is focused on "By-product recovery when oxidizing polymethylbenzenes to polycarboxylic." This invention outlines a method for recovering substantial proportions of methyl acetate and unreacted polymethylbenzene from waste gas produced during the oxidation process. The waste gas is treated by passing it through a bed of activated carbon, allowing for the desorption of valuable by-products. This innovative approach enhances the efficiency of the oxidation process and contributes to waste reduction.
