Latest Patents

Maria holds a patent for a method to treat an ion-exchanger catalyst for the process of bisphenol-A. This method involves controlling the water content of the resultant cation-exchanger bed. The process utilizes an acid ion-exchanger resin in the form of a sulphonated styrene-divinylbenzene copolymer, which is washed with phenol. The washing is then contacted with a basic ion-exchanger resin. Water is removed from the washing by distillation, and the dewatered phenol is recycled to wash the cation-exchanger bed. The catalyst bed is subsequently washed with a mixture of phenol, acetone, and water, which is also recycled to achieve the desired moisture content.

Career Highlights

Throughout her career, Maria has worked with prominent organizations such as the Instytut Ciezkiej Syntezy Organicznej Blachownia and Zaklady Chemiczne Blachownia. Her experience in these institutions has allowed her to develop and refine her innovative techniques in chemical synthesis.
