O. Dapremont

O. Dapremont

Executive Director
AMPAC Fine Chemicals LLC


Dr Dapremont received his Master degree in Chemical Engineering from the University of Toulouse, France and his Ph.D. degree in Chemical Engineering and Applied Chemistry in Simulated Moving Bed technology (SMB) and chiral applications in 1997 from the University of Pierre and Marie Curie in Paris France. He started his career, in 1992, developing SMB technology for Prochrom R&D, France. In 1997, He joined Chiral Technologies Europe, France, as manager of the SMB laboratory, where he was in charge of developing kilogram scale SMB chiral separations. He joined Aerojet Fine Chemicals, now AMPAC Fine Chemicals (AFC) in Rancho Cordova, CA, at the beginning of 2001. At AFC, Dr Dapremont is in charge of the development of chromatographic processes for APIs and intermediates. To this day, he has developed and implemented more than 20 chiral and non-chiral separations using SMB from kilogram to multi ton scale. Dr. Dapremont is author and co-author of several articles on preparative chromatography and SMB applications in various scientific journals and magazines. He is co-inventor for multiple patents using SMB as a purification step for APIs and he has been presenting lectures at International conferences on Preparative Chromatography (Prep, SPICA, Large Scale Chromatography Conference) for the past 20 years. Dr Dapremont is also a member of the Organizing Committee of the Prep Symposium conference and a member of the Scientific Committee of the SPICA conference.

Research Interest

Research interests are in the development of the technology for continuous processes and preferably continuous separations (Chromatography, evaporation, extraction…). The combination of hands-on and theoretical approaches via experimentation and modelling is the preferred interest.
