How can you convert chloro benzene to aniline?
Using Copper I oxide, 200oC and high pressure, reacting with Ammonia
Diazotize with HCl and NaNO2 and then react with H3PO3. - - - - - Outside the educational environment you never convert aniline into benzene because there's no point - aniline is made from benzene and benzene is really, really cheap. So instead of going to the time and trouble of converting benzene into aniline then back to benzene, you just use the benzene the way it comes.
I would like to know too
The first step is a nitration: treat benzene with H2SO4 and HNO3. Then Sn and HCl under heat with a NaOH basic work-up will get you to aniline.
You nitrate the benzene with nitric and sulfuric acids, then catalytically hydrogenate the intermediate. But you're not going to do it at all if you can't raise the intermediate to 300 degrees C.
yes. MCB is mono chloro benzene and has one halogen (chloro) attached to the benzene ring.
Using Wurtz-Fittig reaction of chloro benzene with methyl chloride and sodium metal. However, it is likely that there will be ethane and biphenyl as byproducts.
how to convert aniline to chlorobenzene
Aniline is C6H5NH2 which when reacts with NaNO2, HCl at 273-278K gives C6H5N2Cl which further reacts with H3Po2-H2O/Cu and heated gives benzene whose formula is C6H6.
It is amino benzene: C6H5NH2
With hydrogen in a catalized reaction
The simplest method would be distillation, because bromobenzene has a higher boiling point than chlorobenzene.
Diazotise benzene amine (or aniline) followed by treatment with KCN/CuCN to obtain benzonitrile. Hydrolysis of benzonitrile catalysed by acid will give benzoic acid.
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.
Why is it that aniline has a high boiling point to phenol and phenol has a high boiling point than toluene and toluene has a high boiling point than benzene?
It s the structure and bonding of Aniline, Phenol, Benzene and Toluene that causes the differences in the boiling points.
convert benzene to phenylacetylene
aniline is more acidic because in aniline a electron withdrawing benzene is connected.electron withdrawing capacity of benzene is due to its delocalizing pi electrons cloud.due the action of benzene the presence of unshared pair of electron over nitrogen is somehow decreases.which increases its acidic nature. But in case of ammonia there is no electron withdrawing group.so its unshared pair of electron remains undistrubed,which decreases its acidity and increases its basisity
Partially true because benzene also obtained from other sources.
The lone pair on the nitrogen of aniline is delocalised into the pi-system of the benzene ring and is therefore less available for attack on a proton.
To avoid carcinogenicity by the use of benzene to be chlorinated to become chlorobenzene could it be possible to convert far less toxic toluene to chlorobenzene?
No, it is impossible and useless, besides both chloro-methylbenzene (phenylchloride, as intermediate product) and chlorobenzene (final) are also carcinogenic
benzene with 2~chloropropane in presence of aluminiumchloride
Convert benzene to methyl benzene by reacting it with CH3Cl and anhydrous AlCl3. Oxidize methyl benzene with a powerful oxidizing agent like alkaline KMnO4.
in the case of aniline, the lone pair on nitrogen is involved in resonance with the benzene ring, hence its basicity decreases. no such resonance is seen in cyclohexyl amine, and the lone pair is available to abstract protons and it is stronger base than aniline.
React benzene with nitric acid using sulfuric acid as a catalyst and reduce the product
firstly benzene with HNO3 and H2SO4 and you get nitrobenzene.
when phenol is treated with zinc dust it converts to benzene.....
benzene after oxidation convert into benzoic acid. zahra khan.
Which chloro derivative of benzene would undergo hydrolysis most rapidly with aqueous NaOH to furnish the hydroxy derivative?
For this u should come up with options but still..... here sn2ar mechanism will take place,so for cl to make way for OH benzene should have a good electron withdrawing group attached like no2- at para or ortho position so the best compound would be chloro benzene with no2- at both the ortho position and at the single para position.
Oxidation (with KMnO4) then decarboxylation (with soda lime) of ethyl benzene gives methyl benzene (Toluene) the repetition of same processes with mthylbenzene gives the benzene.
It isn't. Chlorobenzene is prepared by chlorinating benzene. The resulting compound can be nitrated to produce nitrochlorobenzene, which is then hydrogenated to produce chloroaniline.
First convert aniline to diazonium salt using NaNO2/HCl at 0-5 degree C, Then diazonium ion reacts with the water at 100 degree C to produced phenol.
Convert the benzene into Phenol which is a good antiseptic material.
Three. One with them all right next to each other. One with the chloro groups on alternating carbons. One with two chloro groups on adjacent carbons, and one on a non-adjacent carbon.
What is the major product of reaction of 4-Ethyl methoxy benzene in the presence of chlorine and AlCl3?
The major product is 2-chloro-4-ethyl methoxybenzene.
You could use a Sandmeyer reaction: treat aniline with NaNO2 and HCl, which creates a diazonium salt, then use CuBr to form bromobenzene.
By the Friedel Crafts reaction of benzene with methyl chloride and anhydrous aluminium chloride.
Because in Benzylamine : the unshared lone pair of electron on nitrogen atom isavailable >.. But in n-ethyl aniline: the unshared lone pair of electron is not available and enter resonance with benzene ring .(Villa)
The amine lone pair in aniline is conjugated to the benzene ring. Amines are strongly electron donating, so the lone pair is partially "stuck" in the aromatic system. This means that it is less available to latch onto a proton (the definition of basicity).
By Friedel crafts acylation, ie treating benzene with any CH3COX, where X is a halide.
That is a very good question. But it is very hard to explain without the visualization of demonstration.

Aniline (phenylamine) is only slightly soluble in water (3.6g/mL @ 20C). This is a volatile amine. It would be similar to trying to mix benzene with water, or any other typical household solvent/degreaser with water. You would see a separation of the liquids into layers.
1. benzene to nitro benzene through nitration 2. nitro benzene to m-bromonitrobenzene by bromination 3. m-bromonitrobenzene to m-bromoaniline through halogenation in presence of Sn+HCl.
Oxidize the Toluene into Benzoic acid by using KMnO4 and then decarboxylation of benzoic acid with the help of Sodalime produces Benzene.
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).
As there is an availability of lone pair of electrons on chlorine, it directs the benzene ring towards electrophilic substitution at ortho and para positions.. When we will draw the resonating structures of chloro benzene,we will see that negative charge resides at orho and para positions..
Some examples are as follows: * benzene * ethylbenzene * toluene * xylene * m-xylene * p-xylene * aniline * benzoic acid * chlorobenzene * picric acid * nitrobenzene
Cyclohexane can be converted into benzene by catalytic dehydrogenation in the presence of oxides of D block for ex V2O5, Cr2O3 etc. Cyclohexane when heated at 6000C in presence of Al2O3-Cr2O3 gives benzene.
Aniline is a primary amine, and is a weak base like most primary amines (pKb is 9.42). It is a weaker base than comparable primary amines (most have pKb in the 3-4 range) because the amine lone pair on aniline is conjugated to the benzene ring. Remember that amines are strongly electron donating so the lone pair is delocalized into the aromatic system and not quite as available to grab protons (the definition of basicity).
To synthesize acetophenone from benzene, you just need to add the aldehyde to the benzene ring. This can be done via a Friedel-Crafts acylation. The reagents are an acid chloride (acetyl chloride in this case) and AlCl3 (stoichiometric).
do a Friedel Crafts alkylation with ethyl halide and AlCl3.
