On the model-based design and comparison of crystallization-based deracemization techniques

چکیده

Deracemization techniques produce target enantiomer (eutomer) by converting the undesired (distomer) through a racemization reaction. We identify four differing in operation mode and temperature profile. The novel ”MSMPR-type deracemization” process consists of continuous seeded crystallization coupled with racemization. A steady state model enables us to feasible operating region spanned feed concentration residence time, at different kinetics temperatures. analysis shows that most productive point corresponds least robust conditions, thus revealing trade-off between productivity purity. Based on this study, which complements integrates our previous contributions crystallization-based deracemization, we clarify characteristic features each compare processes case study. results demonstrate cooling outperform cycles terms yield, but latter provides larger purity if distomer nucleation cannot be avoided.

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
