1st experiment - Distillation under Total Reflux Conditions
1. Pour 5L of ethanol and water binary mixture into the reboiler.
Group Discussions :
1. Discuss what you have achieved through the completion of this project by considering both personal and academic development.
2. Describe how the design of your experiment or the design if your product allowed you to achieve the project's desired outcomes.
3. Identify the possible limitations (restrictions) to your project through the consideration of the design of your experiment or the design of your product.
4. Suggest possible improvements that could be made in order to minimize the limitations identified.
- RESULTS -
This is the data obtained from the Bottom and Top Product Receivers. We took a sample from the product receivers and used the Gas Chromatography machine to process the data.
Reflux Ratio was 5:1, set using the control machine.
We derived the percentage of water and ethanol (and Methanol*) using the formula provided.
To derive the percentage of water
- (Area - 15.83152)/525331623 = Amt of water
To derive the percentage of ethanol
- (Area - 70.827344)/1384553014 = Amt of ethanol
The percentage would be, 21.8% Ethanol, 78.2% Water and 65.8% Ethanol, 34.2% Water.

This experiment provided us with the data of 18.5% Ethanol, 83.5% Water and 75% Ethanol and 24.9% Water from left to right.
After this experiment, we manipulated another of the variables, amount of heat used.From this we got our second set of results.
The percentage would be, 21.8% Ethanol, 78.2% Water and 65.8% Ethanol, 34.2% Water.
