Latest Patents

Among Sudipto Majumdar's latest inventions are two noteworthy patents:

1. **Processes for separation of aromatic compounds using a thin film composite membrane** - This invention presents a novel method for effectively separating an aromatic compound from a mixture with an alkane. The improved thin-film composite membrane is especially efficient for separating benzene from cyclohexane, despite their similar boiling points. The membrane's enhanced durability and defect-free characteristics stem from its fabrication using an ionomer solution that is mostly free from dissolved ionic species unrelated to the ionomer.

2. **Isomer separation with highly fluorinated polymer membranes** - This patent describes the separation of linear and branched alkane isomers through selective permeation via a composite membrane. The separation layer is crafted from a blend of two distinct fluoropolymer compositions. Composition A exhibits greater permeability for normal-alkane isomers compared to composition B, while composition B provides equal or superior selectivity for normal alkanes over branched isomers. The resulting composite membrane is highly effective in the desired separation processes.
