Latest Patents

One of Toru Sato's key patents is titled "Process for separation of naphthoquinone and phthalic acid." This innovative process allows for the separation of naphthoquinone with a purity exceeding 95% from an aqueous slurry containing both naphthoquinone and phthalic acid. The method involves contacting a reaction mixture gas with an aqueous medium, which is formed by the catalytic vapor phase oxidation of naphthalene. The extraction of naphthoquinone is performed using a chain or cyclic saturated hydrocarbon at temperatures ranging from 60 to 110 degrees Celsius, while adjusting the pH to between 1.2 and 5. This process effectively dissolves phthalic acid in the aqueous phase, leaving resinous materials as a residue.
