Title: Eija Ahonen: Inventor in Cellulose Chemistry.
Introduction
Eija Ahonen is an inventor associated with Espoo, Finland, and Kemira Oyj. Her patent work concerns cationized cellulose, a modified cellulose material produced through a chemical process.
Latest Patents
Ahonen is associated with 1 patent: “Method for Producing Cationized Cellulose and Cationized Cellulose.” The invention describes preparing a concentrated slurry of cellulosic starting material in an alkaline liquid medium containing an organic liquid, then mercerizing the slurry. After mercerization, a cationizing agent is added at a temperature below the medium’s boiling point, allowing the cellulose to react and form cationized cellulose. The reaction may be carried out under an inert atmosphere.
Career Highlights
Ahonen’s listed patent reflects work on methods for modifying cellulose and producing cationized cellulose. The disclosed process specifies a cellulosic starting-material concentration of at least 20 weight percent, calculated on a dry basis relative to the total weight of the liquid medium and starting material.
Collaborations
Ahonen’s listed coworkers include Veli-Matti Vuorenpalo and Jonni Ahlgren. Her company affiliation is Kemira Oyj.
Conclusion
Eija Ahonen’s patent work focuses on a process for producing cationized cellulose through slurry preparation, mercerization, and subsequent cationization.
