How do you separate benzoic acid from a mixture of benzoic acid and toluene using extraction?
Make a solution of Sodium Hydroxide or Sodium Carbonate and do three to four solvent solvent extractions using the aqueous base and the mixture o benzoic acid and toluene. Because benzoic acid reacts with base to form the water soluble carboxylate ion, it will react and the dissolve in the aqueous solution. Upon separation of the two phases acidify the aqueous extract with dilute HCl, a white needle-like precipitate of benzoic acid will form when the solution becomes acidic. Simply filter the crystals, wash with cold water, and then recrystallize using a mixture of 50/50 water and methanol or some other suitable solvent.
Which is more acidic formic acid or benzoic acid?
Benzoic Acid
Why o-hydroxy benzoic acid is strong than m-hydroxy benzoic acid?

What is the eutectic temperature for benzoic and mandelic acid?
The eutectic temperature for benzoic acid and mendelic acid mixture is 105-106º C. This is usually about 60% mandelic acid and 40% benzoic acid.
Is benzoic acid a strong or weak acid?
Yes. Benzoic acid is an organic compond with the formula C7H5CO2H
Process of preparation of benzoic acid?
Benzoic acid is produced from toluene and oxygen. The toluene is oxidyzed and a water molecule is released, which resuls in benzoic acid source: wikipedia
Why toluene does not react with acidic or alkaline permanganates?
Toluene reacts with acidic permanganate on heating and forms the Benzoic acid.
Where does sodium benzoate come from?
Sodium benzoate is manufactured by reacting benzoic acid with sodium hydroxide. Benzoic acid is produced by partial oxydation of toluene with oxygen. There are half a dozen ways or more ways to make toluene.

Will toluene and benzoic acid react?
This is a catalysed oxidation reaction at the methyl (CH3-) group of toluene.2C6H5-CH3 + 3O2 --> 2C6H5-COOH + 2H2OI respelled your original question at 3 points! I couldn't find any 'preperation method for bezoic acid from toulene'
How do you convert benzene to toluene?
Toluene + HNO3/H2SO4 --> p-nitrotoluene (para directed nitration) p-nitrotoluene + Zn/HCl --> p-aminotoluene (changing NO2 to NH2 by reduction) p-aminotoluene +Br2 --> bromination ortho to NH2 Remove NH2 via diazonium salt and decomposition with 1) HONO (which is NaNO2+HCl), 2) H3PO2 for the final product.
Is benzoic acid soluble in kerosene.?
Benzoic acid is soluble in kerosene.

Is Benzoic acid intensive or extensive?
Neither. Benzoic acid is... benzoic acid. Intensive and extensive are properties are characteristics of elements and compounds such as color, density, odor, conductivity, etc. To say benzoic acid is extensive or benzoic acid is intensive doesn't make sense.
What is the eutectic temperature for benzoic and mandelic acid?
The eutectic temperature for benzoic acid and mendelic acid mixture is 105-106º C. This is usually about 60% mandelic acid and 40% benzoic acid.
