Green chemistry became an eminent trend in chemical research and industry since Vintage Posters the 1990s, and thus green chemistry is also increasingly suggested to become an issue in chemistry education.One of the principles of green chemistry is to use effective catalysis in general, and enzymatic catalysis under mild conditions in particular.This article presents a set of experiments under catalysis by immobilized lipase that were developed and tested in an action research project for developing a Inner Oven Door Seal green organic chemistry curriculum for the senior secondary schooling level in Germany.
