bubbling a gas through a solution

Broken Gears - 8-9-2006 at 05:36

First of all I would just like to say that this is a great site. Lots of priceless info. Even though most of it is far too advanced for a little newbie like me.

I have a some experiments that requires bubbling a gas through a solution. Here are some of em:
Cl2 + ethanol --> chloral hydrate
Cl2 + toluene --> benzyl chloride
N2O + sodium amide --> Sodium azide

But my question is, what is the average rate of bubbles? A bubble pr. sec? It will be a waste just to burst away with the gas, right?
Are there in general a great loss of gas?

Bubbking through something like glasswool sometimes helps to keep te bubbles small and dispersed.

Nothing stops you from recycling the gas.

Call up the good folks at united glass tech and have them custom make you a glass inlet adapter with a fritted fitting on the end.

Last I checked they could make one for around $45.

Could you by any chance show me a picture of one? Maybe even the whole setup for bubbling gas.
