Kontinuierliche Durchflussverfahren: ein Werkzeug für die sichere Synthese von pharmazeutischen Wirkstoffen

Abstract: In den letzten Jahren haben Durchflussreaktoren mit Kanalabmessungen im Mikrometer‐ oder Millimeterbereich weitverbreitete Anwendung in der organischen Synthese gefunden. Diese Reaktoren sind durch ihre außergewöhnlich schnellen Wärme‐ und Stoffübertragung gekennzeichnet. Außer bei den schnellsten Reaktionen kann in mikrostrukturierten Bauelementen dieses Typs eine fast augenblickliche Vermischung der Reaktanten erreicht werden. Ebenso lassen sich Probleme wie Wärmestau, Überhitzungszonen (Hot‐Spots) und therm… Show more

“…14 Takav pristup ima obećavajuće prognoze za rješavanje aktualnih i vrlo osjetljivih društvenih problema: nedostatak lijekova (slika 5), dostupnost u udaljenim područjima, spori razvoj novih i slaba ulaganja u lijekove za rijetke bolesti te previsoki troškovi proizvodnje za zemlje u razvoju. [15][16][17][18][19][20] Mogućnost kontinuirane proizvodnje lančanim procesima od sinteze aktivnog sastojka do konačnog lijeka omogućuje pouzdaniji i učinkovitiji proizvodni proces s boljom ponovljivosti. Fleksibilnost procesa koji se provode u protočnim sustavima omogućava proizvodnju lijekova s obzirom na potražnju.…”

“…Thea bility to manufacture high-potency molecules in as afer,m ore-controlled environment, often in previously unachievable purity,i sw hy this synthetic format has been embraced by pharmaceutical manufacturers,a nd deemed by the United States Food and Drug Administration (USFDA) as an emerging technology that will lead pharmaceutical modernization in the future. [1][2][3][4][5] Thed ynamic nature of CM, which comprises av ariety of moving mechanical components,f orces manufacturers to thoroughly understand process dynamics as af unction of various feed attributes (purity of raw materials,m aterial flow properties,e tc. ), transformation conditions (mass-and energy-transfer behaviors,l aminar versus turbulent flow,e tc.…”
