   Peer-reviewed journal | 05 Sep 2024 | Contributor(s):: Wei-Lee Wu, Zoltan K. Nagy, Yash Barhate, Hemalatha Kilari

   A systematic digital design framework for the development of a digital twin of a continuous crystallization process was presented using the model compound, diphenhydramine hydrochloride (DPH). The key features of the framework include operating space investigations, kinetic parameter estimation...

2. End-to-end continuous flow synthesis and purification of diphenhydramine hydrochloride featuring atom economy, in-line separation, and flow of molten ammonium salts†
