Latest Patents

Mummaneni's latest patents focus on innovative processes for making polyethylene terephthalate. The first patent describes a method that utilizes a mixed metal catalyst system to produce PET from ethylene glycol (EG) and purified terephthalic acid (PTA). This process involves esterifying EG and PTA to form diethyleneglycol terephthalate and oligomers, followed by melt-phase polycondensation to yield PET. The catalyst system consists of specific amounts of antimony, zinc, and titanium compounds, allowing for high productivity and favorable optical properties in the final product.

The second patent also outlines a process for producing PET, but it incorporates a different catalyst system that includes antimony, zinc, and phosphorous compounds. This method similarly involves esterification and polycondensation steps, resulting in PET with excellent color and clarity, while minimizing acetaldehyde regeneration during melt-processing.
