Distillation Flashcards
1
Q
What is the function of “distillation?”
A
to separate molecules that have significantly different boiling points
2
Q
What technique is used for molecules that differ by 25 Celsius or GREATER (25+)?
A
simple distillation
3
Q
What technique is used for molecules that differ by 25 Celsius or LESS (25-)?
A
fractional distillation
4
Q
What technique is used for molecules with high boiling points that are at risk of decomposition?
A
vacuum distillation
-this is done under reduced pressure, allowing the mixture to boil at a lower than normal temp
5
Q
Why is an oil bath often used?
A
because at high temperatures the oil won’t evaporate, and it allows for a constant temperature
