I realized a reaction of mixed aldolisation between acetone and 2-nitrobenzaldehyde, using a solution of 10% NaOH in ethanol.
I obtained a mixture of products at the end of the reaction. The problem is when I added the ethyl acetate I saw a blue liquid mixed with brown solid. After a night of this reaction I found a lot of white crystals mixed with the blue liquid.
Can someone explain the presence of this blue liquid with the brown solid, knowing that the crystals are soluble in ethanol?
