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.
What else can I help you with?
How do you convert toluene to benzoic acid?
Toluene can be oxidized to benzoic acid using a strong oxidizing agent, such as potassium permanganate (KMnO4) or chromic acid (H2CrO4). The reaction typically occurs under acidic conditions. The methyl group of toluene is oxidized to a carboxylic acid group, resulting in the formation of benzoic acid.
How does benzoic acid form dimer in toluene layer?
Benzoic acid can form dimers in a toluene layer due to hydrogen bonding between the carboxylic acid groups of adjacent molecules. The aromatic ring structure of benzoic acid allows for efficient packing in the toluene layer, promoting dimer formation. This dimerization process is driven by the favorable interactions between the molecules, such as hydrogen bonding.
How do you separate water and toluene?
Add Aqueous sodium hydroxide to the mixture then shake the mixture with excess of water separate the two liquid layers by separating funnel then add HCl to water layer evaporate the water and get the phenolic compounds.
What use of toluene displacement method?
This method is used for the determination of True density of the particles i.e Grains, any liquid substance etc. True density refers the density of the material with compaction. The value is always higher than Bulk density.
Is toluene a pure substance or mixture?
Toluene is a pure substance because it is a single compound with a uniform chemical composition throughout.
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.

Is toluene a element or mixture?
Neither. Toluene is a compound.

In liquid liquid extraction what factors you consider to choose select the proper solvent as an example consider the extraction of benzoic acid from water?
In choosing a proper solvent for liquid-liquid extraction of benzoic acid from water, factors to consider include solubility of the solute in the solvent, density difference between the solvent and water for easy phase separation, and the ability of the solvent to form a distinct phase with water. In this case, a non-polar solvent like diethyl ether or ethyl acetate could be suitable as they have good solubility for benzoic acid and can form a separate layer with water for easy separation.
What happens when toluene is treated with alkaline KMnO4?
When toluene is treated with alkaline KMnO4, it undergoes oxidation. Toluene is converted to benzyl alcohol, and further oxidation can convert benzyl alcohol to benzoic acid. The purple color of the KMnO4 solution will fade as the reaction proceeds.
What will happen if toluene react with potassium per magnate in presence of sodium carbonate?
When toluene reacts with potassium permanganate in the presence of sodium carbonate, the permanganate will oxidize the toluene to form benzoic acid. The sodium carbonate will help neutralize any acidic byproducts formed during the reaction.
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.
