You can prepare phenyl at home. Here is an outline of the process of its preparation. Study it and describe the process: Hints: [Mixing crushed resin with boiled castor oil—cooling—mixing caustic soda solution – stirring solution frequently—pouring creosote oil—leaving it for 10 minutes—adding carbolic acid and potassium permanganate—pouring water—stirring the solution—pouring into another pot—leaving it for 24 hours]
