You wish to purify by distillation a material that has a boiling point of 205 C and reacts with air but this material will decompose if heated above 150 C. How would you set up the system to distill this material?
Show steps Pleaseeeee!!!!!!!!!!
Thank you!!!!
There are no "steps" per se except to set up a vacuum distillation apparatus. We can't draw structures on this forum but you can Google "vacuum distillation apparatus image" and obtain several nice pictures. I can find some if you can't.
To set up a distillation system to purify a material with a boiling point of 205°C but decomposes if heated above 150°C, you can follow these steps:
1. Start by assembling a simple distillation apparatus consisting of a round-bottom flask, a distillation head, a condenser, a receiving flask, and a heat source (such as a hot plate).
2. Connect the round-bottom flask to the distillation head, which connects to the condenser. The condenser should be attached to a water source for cooling.
3. Place the material you wish to distill in the round-bottom flask. It is crucial to use a flask that can withstand the intended temperature range.
4. Ensure that the receiving flask is appropriately positioned to collect the distillate.
5. To prevent decomposition of the material, it is important to control the temperature carefully to keep it below 150°C. This can be achieved by using a thermometer and a temperature control device (such as a temperature controller or variac). Set the temperature control device to maintain the temperature below 150°C.
6. Apply heat to the flask using the heat source gradually. Start with low heat and gradually increase it while monitoring the temperature.
7. As the temperature rises, the material will start to vaporize. The vapor will ascend through the distillation head and condense in the condenser. The condensed liquid will then collect in the receiving flask as a purified distillate.
8. Continue distilling until the temperature reaches around 205°C, or slightly below, to collect the most volatile and pure fraction. Be cautious not to exceed the temperature range to avoid decomposition.
9. Once the distillation is complete, remove the receiving flask containing the purified distillate and stop the heat source.
It is important to note that every material has unique characteristics, and the specific equipment setup and conditions may vary. It is recommended to consult specialized literature or seek expert advice for handling specific materials to ensure safety and achieve desired results.
