A continuously operating spinning disk reactor (SDR) displayed distinct advantages over batch
processing techniques when several commercially relevant processes for the manufacture of
pharmaceuticals as test reactions were investigated. It proved to be a useful tool for revealing
intrinsically fast kinetics as well as for optimizing processes with such kinetics. Very encouraging
results were achieved for a phase-transfer-catalyzed (ptc) Darzen's reaction to prepare a drug
intermediate and the recrystallization of an active pharmaceutical ingredient (API). In
comparison to presently used batch processes, the ptc reaction resulted in a reaction with 99.9%
reduced reaction time, 99% reduced inventory, and 93% reduced impurity level. The recrystallization yielded particles with a tight particle size distribution and a mean size of around 3 μm.
Reactor modeling was in good agreement with the experimental results and highlighted the
advantages of the process-intensified equipment with a production capacity of around 8 tonnes/year.
The bilateral GPM technique improves in a short term the self-perceived low back pelvic pain, the PPT in both SIJs, and the serotonin levels in women with PD. It shows no significant differences with a sham intervention in catecholamines plasma levels.
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.
