Latest Patents

Lee's latest patents focus on innovative methods for manufacturing terephthalic acid. The first patent, titled "Method for manufacturing terephthalic acid," outlines a process that includes providing a titrant receptor solution, which is water. The method involves adding disodium terephthalate aqueous solution and an acid titrant into the titrant receptor solution to form terephthalic acid crystals and an end-point solution. The final step is the separation of the terephthalic acid crystals from the end-point solution.

The second patent, "Method for manufacturing terephthalic acid and system thereof," describes a more complex process. This method begins with providing a raw material that includes polyethylene terephthalate. A depolymerization reaction is performed on this raw material to create a depolymerization product, which consists of disodium terephthalate. Following this, a decolorization process is conducted to produce decolorized disodium terephthalate and precipitated sludge. The final steps involve separating the decolorized disodium terephthalate from the sludge and forming terephthalic acid from the decolorized product.
