An example for an equation for the reactions used to separate and recover m-nitroaniline benzoic acid and naphthalene is RCO2H + NaOH RCO2 - Na+ (water soluble salt) + H2O (eq. 1)
One way to separate naphthalene from sand is by sublimation. By heating the mixture, the naphthalene will undergo sublimation, turning into a gas and leaving behind the sand. The gas can then be collected and cooled back into solid naphthalene.
Sublimation can be used to separate naphthalene from sand. Naphthalene can be heated to change it directly from a solid to a gas, leaving the sand behind. The gas can then be collected and cooled to form solid naphthalene again.
Naphthalene can be separated from sodium chloride by sublimation. When the mixture is heated, naphthalene will sublimate, turning from a solid to a gas, and can be collected separately from the solid sodium chloride.
One way is to slurry the solid mixture with water. The ammonium chloride will dissolve and the naphthalene will not. Ammonium chloride can then be recovered by evaporating the water solution of it that is formed.
Iron filings removed magnetically. Water will dissolve sodium chloride and suspend sand. Sand can be filtered out of the solution, and salt reovered by evaporation of water. Naphthalene can be removed separately if necessary by solution of mixture in alcohol.

Sublimation can be used to separate naphthalene from chalk powder. Naphthalene sublimes at room temperature, while chalk powder does not, allowing for the separation based on this difference in physical properties.
by melting them through distillation

Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
One possible way to separate naphthalene and potassium bromide is through sublimation. Naphthalene can be sublimed by heating the mixture, allowing it to vaporize and then condense back into solid form. Since potassium bromide does not sublime easily, it would remain in the solid state and can be separated from the naphthalene vapor.
To separate naphthalene balls from sodium chloride, simply add water until all the sodium chloride is dissolved. Then either filter, or just pour off the solution, and the naphthalene balls will be left behind. Naphthalene is very insoluble in water, and sodium chloride is very soluble in water.
Filtration because it says that it can separate fine solid from liquids.
Sublimation is a process where a solid directly turns into a gas without going through the liquid stage. To separate naphthalene and ammonium chloride by sublimation, heat can be applied to turn naphthalene into a gas, leaving ammonium chloride behind as it does not sublimate. The gas can then be collected and cooled back into a solid.
When naphthalene and glycerin are mixed, naphthalene, a solid hydrocarbon, does not dissolve well in glycerin, which is a polar liquid. Instead, the naphthalene may float on top or form a separate layer, as it is less dense than glycerin. Additionally, the two substances do not chemically react, so the mixture remains physically distinct without forming a new compound. The result is a heterogeneous mixture with naphthalene crystals suspended in the glycerin.
