Toluenesulfonyl chloride: Why within ice?
« on: September 08, 2011, 02:12:47 PM »
Why do you have to put Toluenesulfonyl chloride into ice when doing a reaction with it?
The boiling point is 134°C, so it would be liquid at room temperature, wouldn't it?

The key here is the "doing a reaction with it" part.

Why would you cool a reaction?
Individual results may vary

To absorb the energy from the reaction and to stop other unwanted reactions?

Yes, TsCl usually reacts quite rapidly and exothermically, so cooling is generally employed to slow down the reaction and prevent a runaway exotherm (which may lead to unwanted side reactions).

The melting point of TsCl is ~65oC by the way, it's a crystalline solid at rtp.
