Reaction Product of Nitric acid plus Sulphuric acid


A discussion started in 2006 & continuing through 2017 . . .

(2006)

Q. What is the product of nitric acid and sulphuric acid?

A. There is no chemical reaction. H + NO3 and H2 + SO4 will give an equilibrium of the ions and the acid. Now, it is possible that if you add concentrated sulfuric acid to the nitric it can become hot enough to break the HNO3 into water and NO2 (gas). Has to do with heat, not a reaction between the two.

A. Mixing of nitric and sulphuric acid ... fairly boring on its own. Now, if we consider this in the context of organic chemistry we have a nitrating mixture. When heated in the presence of organic materials we form the nitrating radical, used for nitrating a number of organic compounds such as phenol, toluene and benzene.

Nitronium ion

Q. I want to about mechanism of formation of nitronium ion by the reaction between sulfuric acid (98%) and nitric acid (98%).

A. Hi Saurabh,

Nitronium ion (NO2+)is formed by below reaction:

2 H2SO4 + HNO3 => 2 HSO4(−) + NO2(+) + H3O(+)

How to make 2EHN

September 14, 2016

Q. Hi, I want to produce 2EHN. How can I do it?
I have mixed H2SO4 and HNO3(2:1 ratio)...
What should I do next?
Thank you

A. The fact that you have started mixing acids without knowing what to do next tells me that you have no idea what you are doing and how hazardous this process can be.
Nitrating organic materials is a job for a qualified organic chemist with facilities to prevent thermal runaway with probably explosive results.
I suggest that you get qualified and competent expert advice and never start a chemical process without clearly knowing everything about the reaction and adequate means to control it and to safely dispose of the waste products.

A. The mixture of nitric acid and sulphuric acid is known as aqua regia.

Hi luchifer. Actually, aqua regia is a mixture of nitric acid and hydrochloric acid, in about a 1:3 ratio.

NO2 industrial Production Process

June 14, 2017

Q. Dear Teacher,

I need to produce NO2 for special reaction in industrial scale.
Actually I don't want to produce nitric acid but one of way which I considered can be ostwald's process but finally I don't need nitric acid and just I need NO2.
Another way, also could be Nitric Acid decomposition on mid temperature, it means I can proceed ammonia decomposition on Pt catalyst to produce No and then to NO2, if the reaction atmosphere has enough amount of H2O then I will have nitric acid and then by it's decomposition NO2 will be produced.
I would like to have your valuable comment on my uncooked concept to prove it to obtain cooked and feasible solution.
Thanks In advance
