in the presence of con.h2so4 anisole will convert into phenol and hi
Phenol is converted to aspirin by adding carboxylic acid and esterifying the alcohol.
Cumene is the common name the IUPAC standard name is Isopropylbenzene
phenols can be prepared by the following methods. 1) hydrolysis of cholorobenzene: in this process, chlorobenzene which can be obtained by the cholorinationof benzene, is heated at 350*C under high pressure with aqueous sodium hydroxide to get sodium phenoxide, which on acidification yields phenol. 2) pyrolosis of sodium benzenesulphonate: this, the first commercial process for industrial synthesizing phenol , was developed in Germany in 1890. sodium benzenesulphonate is melted with sodium hydrooxide at 350*C to produce sodium phenoxide, which on acidification yields phenol. 3) oxidaton of cumene: benzene is alkylated with propene to produce cumene, which is oxidized with air to produce cumene hydroperoxide, which on treatment with 10% sulfuric acid undergoes a hydrolytic rearrangement to yield phenol and acetone.
very easy, a single step reaction. When phenol is heated with Concentrated Nitric acid 2,4.6-trinitrophenol (Picric acid) is produced.
This molecular formula is C9H12.
Convert the benzene into Phenol which is a good antiseptic material.
I'd do it this way. Use Dow's Process (NaOH) to convert chlorobenzene to phenol. Now, use nitrating mixture to get both o and p- nitrophenol. Fractional distillation should give you what you finally need.

The name of this reaction is Friedel-Crafts acylation. It should have a major product adding a ketone at the para position with regard to the isopropyl of the cumene.
The chemical formula of cumene is C9H12.
React aniline with HCl/NaNO2 (diazotisation) followed by reaction with KOH to give phenol. Nitration of phenol with fuming nitric acid gives picric acid (or trinitrophenol).
