The reaction product is analyzed to determine how changes in these parameters change yield, purity, and economics of the proposed process. This information can then be utilized to fine tune the reaction to maximize key parameters for a commercial scale reaction process or simply be used for repetitive laboratory scale applications. Examples demonstrating the utility of a High Pressure Reaction Unit for traditional organic synthesis and supercritical fluid synthesis are presented.

Coprecipitation of active pharmaceutical ingredients (API) with additives can provide the ability to add functionality to API’s at early stages of drug discovery and synthesis. It is with this objective that a number of drugs were recrystallized in the presence of structurally related additives. The rapid expansion of supercritical solution (RESS) process was evaluated to recrystallize the drug–additive mixtures. Results of RESS aided coprecipitation studies involving twelve drug–additive mixtures are reported in this manuscript. Characterization of these mixtures revealed a number of interesting phenomena. These include habit modification, solubility enhancement, particle size reduction, eutectic formation, reduction in crystallinity, amorphous conversion, hydrate formation, polymorph conversion and selective extraction. In viewing each of these phenomena from an application standpoint, this manuscript serves as proof of concept for altering the physicochemical and mechanical properties of API’s using supercritical fluid (SCF) coprecipitation. It was concluded from these studies that the rapid crystallization conditions offered by the SCF media alone does not provide the ability to consistently dope crystals. Competing mechanisms based on the relative solubility of drugs and additives in SCF media, as well as the selectivity of SCF solvents are to be taken into consideration while undertaking coprecipitations.

This review discusses the recent developments in the application of supercritical fluid technologies for the production of composites or encapsulates of bioactive compounds. Various supercritical particle formation technologies are briefly described, including processes in which the supercritical fluid acts as a solute, solvent, and antisolvent. The main features and mechanisms of antisolvent techniques that contribute to the understanding of the fundamentals of the Supercritical Fluid Extraction of Emulsions (SFEE) process are described. The published literature on SFEE, including the results and perspectives of its application in various industrial fields, are discussed. This article is the first comprehensive review specifically focused on the formation of particles using the SFEE technique.
