The Case for Biodiesel with Selected Experiments

Matthew N. Van Kouwenberg

Published September 2006

Tools for this Unit:

Laboratory #4

Take a carbonated beverage and pour equal amounts into 2 Erlenmeyer flasks and stop them with a single holed stopper with tubing attached. Heat one of the flasks to 80?C for about 15 minutes while keeping the other at room temperature.

Then attach a gas pressure gauge to the tubing. Heat both bottles to 80?C for 10 minutes. There should be a higher pressure in the previously unheated flask because the CO 2 , that was previously unreleased will come out.

If you do not have a gas pressure gauge to use, you can trap the escaping gas in a water filled bottle as in Lab 3. Also, instead of heating one of the flasks, you could leave one flask out overnight and the other in a fridge overnight, but if you do this make sure your building does not get too cold overnight.
