Title: Triisobutylaluminium
Post by: CrazyGoat on March 05, 2021, 03:12:03 AM

 I have to handle pure Triisobutylaluminium, I KNOW I can not open the flask in a non-innert atmosphere or within high levels of moisture, for that I will use a glove box dried with a bag of calcium chloride and fulfilled with CO2!! after doing a vacuum to it.

 A friend has told me that it reacts with co2 also, that I need to use argon if I don't wanna die.

 opinions?

N2 should be fine?

So it reacts with Co2.

Aluminum alkyls are know to react with CO₂:
https://echa.europa.eu/registration-dossier/-/registered-dossier/11385/9
"Inert gases suitable for handling of aluminium alkyls are nitrogen and argon. Even carbon dioxide is capable to react with aluminium alkyls although reaction is relatively slow. Therefore carbon dioxide may be used as fire-fighting agent for small spillages in laboratories."
