Title: Dyeing CO2 Gas
Post by: jpothomson on December 19, 2017, 08:20:18 PM

Hi Guys,

I'd like to start off by saying I'm not overly proficient in chemistry - I did high school chemistry about 5 years ago but haven't really followed it up since then.

I currently have a project I'm working on which would require CO2 gas passing through a car exhaust to bond with a chemical dye so that it becomes visible as it exits the exhaust.

I've done a quick Google search and it looks like some sort of dichlorotriazine dye might be the answer but I was wondering if anybody could help give me a steer on how best to approach this problem or if it's even possible at all?

Thanks in advance for your help,
Pierce

Do you need it to specifically react with CO₂, or do you just need exhaust gases to be visible? The latter can be much easier, there are smoke systems designed for that.

Hey there, thanks for your response :)

It would need to react with CO2 to give the project authenticity, do you think it's possible?

Probably very difficult, CO₂ is quite inert.
