With dilute nitric acid at low temperature (298 K), phenol yields a mixture of ortho and para nitrophenols. The isomer can be separated either by steam distillation or fractional crystallization.
Dilute HNO3 with phenol. A mixture of o-nitrophenol and p-nitrophenol is formed. Give the equations of reaction for the preparation of phenol from cumene. Cumene is oxidised into cumene hydro peroxide by air at high pressure which on decomposition by aqueous acid gives phenol and acetone.

Originally Answered: What happens when phenol reacts with dilute HNO3? When phenol reacts with dilute nitric acid at room temperature, electrophilic substitution occurs to form a mixture of 2.
(i) With dilute nitric acid at low temperature (298 K), phenol yields a mixture of ortho . and para nitrophenols. (ii) With concentrated nitric acid, phenol is converted to 2,4,6?trinitrophenol. The product is commonly known as picric acid.

Dilute nitric acid reacts with phenol and produce a mixture of 2-nitrophenol and 4-nitrophenol. With concentrated nitric acid, phenol gives 2,4,6-trinitrophenol as the product. Metals and dilute nitric acid reaction. Dilute nitric acid act as a typical acid when it reacts with a reactive metals such as sodium, magnesium, zinc and more. But nitric acid behaves differently (as an oxidizing acid) with less reactive.
With dilute nitric acid. Phenol reacts with dilute nitric acid at room temperature to give a mixture of 2-nitrophenol and 4-nitrophenol. With concentrated nitric acid. With concentrated nitric acid, more nitro groups substitute around the ring to give 2,4,6-trinitrophenol (old name: picric acid).
8/27/2020 · Direct nitration of phenol (hydroxybenzene) by dilute nitric acid gives modest yields of nitrated phenols and considerable oxidative decomposition to tarry materials; aniline (aminobenzene) is largely destroyed. Bromination of both phenol and aniline is difficult to control, with di-.
Phenols react with halogens to yield mono?, di?, or tri?substituted products, depending on reaction conditions. For example, an aqueous bromine solution brominates all ortho and para positions on the ring. Likewise, you can accomplish monobromination by running the reaction at extremely low temperatures in carbon disulfide solvent.
