Sodium nitrite and hydrochloric acid is added to Aniline at very low temperatures ( 0–4ºC) to form a benzene diazonium ion (a diazonium salt). b. This diazonium salt in presence of leftover hydrochloric acid is further treated with Copper Chloride which forms Chlorobenzene.
When chlorobenzene is heated in the presence of concentrated sodium hydroxide (NaOH) at 300°C under high pressure, it results in the formation of sodium salt of phenol which n acidic medium leads to the formation of free phenol. This process is known as Dow's process.
Optical density is the degree to which a refractive medium retards transmitted rays of light.
