Abstract:Predictions of the purity and yield of a solid product by solid−liquid separation, such as reaction crystallization and extraction, can accurately be captured if the solid−solid−liquid ternary phase diagram of the product-impurity-solvent system is available. However, constructing the phase diagram with tie-lines experimentally is tedious, time-consuming, and unsuitable for solvent selection during early process development. In this work, a mathematical model for predicting the purity and yield of a given solv… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
