Kohlensäure: Erstmals gasförmig isoliert

(PresseBox) (Innsbruck, )
Wissenschaftler der Universität Innsbruck und der TU Wien haben erstmals im Labor gasförmige Kohlensäure hergestellt und isoliert. Die Chemiker um Thomas Lörting (Innsbruck) und Hinrich Grothe (Wien) konnten die gasförmigen Moleküle mittels Infrarotspektroskopie exakt charakterisieren. Die Ergebnisse wurden in der Zeitschrift Angewandte Chemie International Edition veröffentlicht.

Lehrbücher und Medien verbreiten es immer wieder: Stabile Kohlensäure gibt es praktisch nicht. Sie lasse sich in reiner Form nicht erzeugen und zerfalle beim Verdampfen sofort in Kohlendioxid und Wasser. Innsbrucker Chemiker um Erwin Mayer (Institut für Allgemeine, Anorganische und Theoretische Chemie) haben dieses alte Dogma der Chemie schon vor einigen Jahren umgestoßen.
