I have a question
I dissolved Acetone and Sulfuric Acid 98% with rate ~1:1
I predict the product is alcohol since oxidability of Sulfuric Acid
(C=O turn to C-OH)
But the solution after reacting doesn't be flammable, it has brown-red color
And I put Sodium Hydroxide into this test tube, it has heat energy so big
now I can't know properties of this compound
Everyone please explain about my prediction
Sorry for my bad English
Best Regards

Sulphuric acid is not an oxidant.
Sodium hydroxide reacts with sulphuric acid in an acid base process to give a salt and water and lots of heat!

And the color of product after dissolving, I can't understand it ???

DQD:
First of all, what were you trying to achieve with this experiment?
Concentrated sulfuric acid can act as an oxidant, especially toward metals. However, the process you described (C=O turns to C-OH) is a reduction, not an oxidation.
By mixing acetone and sulfuric acid, you probably made a carbonaceous resin by multiple aldol condensation/other side reactions.

Not of any significance, some decomposition, nothing else

Yeah, now I understand it
I have mistake in reduction and oxidation
and what am I trying to achieve with this experiment ?
I like chemistry, I try to react some chemicals that I have at home
I hope I can become chemical engineer as I wished ;D
thanks all

The self condensation products of acetone/H2SO4 are numerous and far from inconsequential. The major products of the reaction are diacetone alcohol, mesityl oxide, (iso)phorone, mesitylene, and 3,5-dimethylphenol.

The product distribution can be tailored to a certain extent using different catalysts. These methods are used industrially.
The mixture in question is likely to be very complex.
