While the preparation of para nitro acetanilide another minor product formed is ortho nitro acetanilide.
- This reaction is known as electrophilic substitution reaction.
- This reaction falls under nitration.
- Acetanilide is reacted with concentrated nitric and sulphuric acid at 288 K and para and ortho nitro acetanilide as a product is formed.
Ortho nitro acetanilide is separated from para nitro acetanilide by dissolving the solution in ethanol.
- o-nitroacetanilide is more soluble in ethanol as compared to water.
- So, o-nitroacetanilide remains in the initial solvent and during crystallization only p-nitroacetanilide forms crystals and separates out from the mixture.
