I have done an experiment with 2 substances monoethanolamine (MEA) and phosphorus acid (H₃PO₃) but I do not know exact products of this reaction. Could anyone give an idea about this problem?

Itis a normal neutralisation.

Actually, MEA is taken into a mixture of CuSO₄ and H₃PO₃. I saw a white cloud after reaction. I wonder if it is CO₂ or NOx smoke...

The white cloud is the ammoniumsalt nebula.

You mean [HOCH₂CH₂NH₃]₂HPO₃ is in nebular form?

Correct. The same if you use ammonia gas and HCl gas.

So there is no amoniumsalt in the solution?

Its in the solution as well. The cloud appers because it gets hot during neutralisation.

Could you send me documentaries related to this reaction via my email: hoangnga.0896@gmail.com please. I need to prove the equation to my boss.

This is basic chemistry. Amines react with acids. There is nothing to approve. Look in a chemist book.

Okay. I got it. Thank you very much.

I've been looking for the name of the product you did type but there was no result. Are there any other reactions?

There is only reaction between MEA and phosphoric acid (H₃PO₄) either.

Do we talk about phosphoric acid or phosphorous acid .

The product is Bis(Hydroxyethyl)-ammoniumphosphite

MEA + H₃PO₃
