We took out the heavy artillery in the Physics and Chemistry lab this week to allow the students in Seconde to carry out a very interesting experiment. The students used different equipment such as a fume hood to handle chemicals safely, a bulb cooler, a balloon heater or a separating funnel. The aim of this work was to synthesize the odorant molecule used for example for the Haribo banana candies. The assembly under reflux made it possible to heat the mixture so that the reaction was faster, also while recondensing the vapors so that there was no loss of product.
