Translation of Destillation

I am a little confused with all the different domains and products and options on this website. Thanks a lot in advance for the fast response. It is really crucial to my students and to the other teachers.
In my next message to you I want to write everything in German. Than I will rewrite it in English and we can compare the output. This way you see the text in your mother tongue and in a foreign language.
That is great. Thank you for the support (and for the compliment). Recommendations by universities are always very appreciated, as universities are usually more selective about external resources.
