Why is air condensation used instead of water condensation for the synthesis of Dimethyl 3,4,5,6 Tetraphenylphthalate?...
Why is air condensation used instead of water condensation for the synthesis of Dimethyl 3,4,5,6 Tetraphenylphthalate? Does it have to do with keeping a controlled temperature?
Homework Answers
The air condenser and water condenser both have the same function to condense the liquid that we need from evaporating
If the chemical that we are purifying using distillation method has boiling point below 100°C can evaporate easily so the water cools down the fumes and sends it back into the distillation flask
But here in this case the boiling point of this compound is around 282°C so the chances of it being evporated under normal conditions are very less so the air condenser is enough for this job
I hope this helps. If you have any query or want more detailed explanation, feel free to ask in the comments section below.
