Micoscale chemistry experimentation with a high level group of
Augustinerschule Friedberg:
"Alcohols not for alcoholics"

On 3.11.1999 Dr. El-Marsafy, a professor of Ain Shams University Cairo/Egypt was a guest of "Leistungskurs" chemistry of Augustinerschule Friedberg. He was accompanied by Dr. Peter Schwarz, a former student of the highschool. The two collegues met each other in Egypt five years ago when the former citizen of Friedberg worked as an integrated expert of the Egyptian Ministry of Education.

The Friedberg students attended a workshop using 5-ml vials to make their own micro burners and to produce different compounds of ethanol. Black, white and red plastic beads were welded to make molecule models of alcohols, aldehyde and acetic acid.

Professor El-Marsafy also demonstrated a microscale method of esterification. This experiment was evaluated by molecule models and computer simulations.
