How do you convert toluene to Meta nitrobenzoic acid?
first oxidizing toluene to benzoic acid and then nitration will give product on meta position.
How do you make meta nitrotoluene?
Hydrolysis of 2-nitro 4-methyl acetanilide gives 2-nitro 4-methyl aniline. This compound under goes diazo reaction followed by heating in presence of ethanol , gives the desired product m- nitro toluene .
Which of the following method can be used to convert toluene into xylene?
Transalkylation, as used by the petrochemical industry, is often used to convert toluene into benzene and xylenes. This is achieved through a disproportionation reaction of toluene in which one toluene molecule transfers its methyl group to another one.
How will you convert toluene into benzene?
1) Oxidize it to benzoic acid using potassium permanganate. 2) Heat the benzoic acid with soda-lime. You will get first sodium benzoate, PhCOONa, and then benzene: PhCOONa + NaOH —–> PhH + Na2CO3.
How is benzoic acid converted to M nitrobenzoic acid?
Answer : When benzoic acid reacted with nitrating mixture it forms m- nitrobenzoic acid further it treated with SOCl2 it chlorinate the acidic COOH group. And reacting with NaBH4 further it get converted into m-nitroenzyl alcohol.
How do you make B nitrotoluene from benzene?
The mixture of p-nitrotoluene and o-nitrotoluene can be separated by fractional distillation. Thus, benzene is converted p-nitrotoluene by converting benzene to toluene then toluene to a mixture of o-nitrotoluene and p-nitrotoluene and then separating the mixture by fractional distillation to get p-nitrotoluene.
How is toluene converted to phenol?
Step 1: Phenol on distillation with zinc dust give the corresponding aromatic hydrocarbons. Step 2: Now, benzene is treated with CH3Cl, to form toluene.
How will you convert I benzene to p nitrotoluene?
What is the formula of xylene?
C₈H₁₀Xylene / Formula
What is xylene solvent?
Xylene is an aromatic hydrocarbon widely used in industry and medical technology as a solvent. It is a colorless, sweet-smelling liquid or gas occurring naturally in petroleum, coal and wood tar, and is so named because it is found in crude wood spirit (Gr.
Which reagent will you use to convert toluene into benzyl chloride?
Free radical chlorination of toluene with chlorine in presence of ultraviolet light or heat give benzyl chloride.
How is benzaldehyde converted to benzophenone?
Hint: When we do the oxidation of aldehyde, it is converted into carboxylic acid. And then by decarboxylation it gets converted to aromatic hydrocarbon. Then if we treat it with benzoyl chloride, we get the desired result.
How to change from toluene to meta nitro touene?
The following method of change from toluene to meta nitro toluene is given below, Toluene first should be converted to Benzoic acid by treating with KMnO4. This helps remove the – COOH group and forms benzene. This is known as Soda lime decarboxylation .
How to prepare p-nitrotoluene from methylmethane?
The approach could be to 1) methylate with CH3Cl/AlCl3 to give toluene, 2) Nitrate with HNO3/H2SO4 to give mainly p-nitrotoluene. 3) Reduce the nitro to an amino group (Sn/HCl). 4) Acetylate the amino group (Acetyl-Chloride/base). Now you have an o/p-director para to the methyl group.
How to convert toluene to benzoic acid?
Toluene first should be converted to Benzoic acid by treating with KMnO4. This helps remove the – COOH group and forms benzene. This is known as Soda lime decarboxylation . Now Friedel Craft alkylation with CH3Cl in presence of anhydrous AlCl3 gives the required product .
What is the product formed when nitration of toluene is carried out?
Nitration of toluene gives a mixture of ortho and para nitro toluene . Separating the para isomers we add Sn / HCl , which reduced the p-isomer into p-toluidine . When p-toluidine is treated with acetic anhydride it form 4-methyl acetanilide . Now , on further nitration ,it gives 2-nitro 4-methyl acetanilide .
