You hit it with steam, and it will hydrolyze into phenol and hydrochloric acid. This isn't a real common way of making HCl, though; the chloralkali process that gives us sodium hydroxide also throws off hydrogen and chlorine, which can be mixed and exposed to UV light to give HCl. But as an educational setup, it's fine.
Most people get their phenol the old-fashioned way, by oxidizing isopropylbenzene. A big reason for doing it that way is the byproduct of the reaction is acetone. If you condense acetone and phenol, you get bisphenol a, which is required if you want to make either polycarbonate (by reacting it with phosgene) or epoxy (by reacting it with epichlorohydrin). 'Course, you can also sell the acetone and phenol separately because there is great demand for both chemicals.
when phenol is treated with zinc dust it converts to benzene.....
add zinc dust to phenol.it will convert into benzene.then add co.
First treat Phenol with Zinc Dust to obtain Benzene and teh ncarry out Nitation in the pressence of Sulpuric acid and Nitric Acid.

do a Friedel Crafts alkylation with ethyl halide and AlCl3.
C6H5+CHCl3--(-HCl)-->C6H5CHCl2OH+2KOH--(-KCl)-->C6H5CH(OH)3--(-H2O)+Heat-->C6H5CHO(OH)
convert benzene to phenylacetylene
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.
No, it is impossible and useless, besides both chloro-methylbenzene (phenylchloride, as intermediate product) and chlorobenzene (final) are also carcinogenic
The chemical formula of chlorobenzene is C6H5Cl; chlorobenzene don't contain nitrogen.
very easy, a single step reaction. When phenol is heated with Concentrated Nitric acid 2,4.6-trinitrophenol (Picric acid) is produced.
According to wikipedia, chlorobenzene is nitrated on an industrial scale to form a mixture of 2-nitrochlorobenzene and 4-nitrochlorobenzene.

There are many known syntheses of phenol. However, a few simple ones are: 1) hydrolysis of chlorobenzene: - chlorobenzene + water --> phenol + hydrochloric acid 2) oxidation of toluene: - toluene + oxygen --> phenol + carbon dioxide + water 3) oxidation of benzene with nitrous oxide: - benzene + nitrous oxide --> phenol + nitrogen
in the presence of con.h2so4 anisole will convert into phenol and hi
No, it is impossible and useless, besides both chloro-methylbenzene (phenylchloride, as intermediate product) and chlorobenzene (final) are also carcinogenic
Phenol is converted to aspirin by adding carboxylic acid and esterifying the alcohol.
The chemical formula of chlorobenzene is C6H5Cl; chlorobenzene don't contain nitrogen.
The chlorobenzene boiling point is 131 oC.
First add HNO2 or NaNO2+dil.HCl below 5 degrees celcius.Then add CuCl+HCl.
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.
Convert the benzene into Phenol which is a good antiseptic material.
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).
