The identity of the solvent that is used in recrystallization is very important because only if the correct solvent is used, will the product be purified and recrystallized as desired. The product, benzanilide, is soluble in hot ethanol, but not in cold ethanol. Any impurities that are expected to arise from the reaction are not soluble in hot ethanol and soluble in the cold ethanol, and thus it is the perfect solvent for the recrystallization process, as only benzanilide is soluble in it and when it is cooled only benzanilide will crystallize out, while any impurities will be left behind in the solution.

ethanol alone is not a good solvent for this substance recrystallization and the compound has a very low solubility in hot or cold water.so ethanol and water are mixed together as solvent for crystallization of p-dibromobenzene that is soluble in the hot solvent mixed.so the turbidity of the hot solution shows the good mixture of ethanol and water as solvent.
because ethanol dissolve urea at slightly higher temperature and not dissolve the impurities
using boiling water. benzanilide is insoluble.
benzophenone + NH3OHCl --> benzophenone oxime (+acid) ---> beckmann rearrangement --> benzanilide
Definitely not methylene chloride and water as these are not miscible solvents.

it is used as an anti-atherosclerotic agent and also in the manufacture of dyes and perfumes.
The crystallization/recrystallization of sodium chloride from water solutions is frequently used.

ethanol is used in alcohol
Crystallization/recrystallization process can be used.
Definitely not methylene chloride and water as these are not miscible solvents.
One of the physical properties of Benzanilide is that its melting point is 163 Degrees Celsius. Its boiling point is 117 Degrees Celsius. Benzanilide is in the form of white crystals that are like needles.
