benzophenone + NH3OHCl --> benzophenone oxime (+acid) ---> beckmann rearrangement --> benzanilide
using boiling water. benzanilide is insoluble.
The question here is asked in a slightly incorrect manner. Assuming I understand exactly what you meant to ask which is "In a reduction of Benzophenone is Diphenylmethanol created with a 1/1 molar ratio?" then the answer is yes they are. For every mole of benzophenone one mole of diphenylmethanol is created. Benzophenone is a reagent and diphenylmethanol is a product in a reduction of benzophenone reaction. However if you're referring to a reaction which creates BOTH diphenylmethanol and benzophenone as products, then you would need to provide the reagents that create the two.
Benzophenone is partially soluble in hexane. Benzophenone is polar, where as, hexane is nonpolar. "Like dissolves like."
From least to most polar: biphenyl >> benzophenone >> benzhydrol
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.

Benzophenone prevents ultraviolet light from damaging colors and scents in products. Without the use of benzophenone some products would have to be shipped in black or dark packaging for protection.

The carbonyl group of the benzophenone acts as a hydrogen bond acceptor with the alcohol group of methanol.
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.

If you'll take a look at its structure benzophenone is polar but during our laboratory we were able to determine if it's polar or non-polar by TLC. The TLC plate was developed in a mixture of petroleum ether and ethyl acetate with a 9:1 ratio respectively. This would mean that the solvent used is non-polar due to the large amount of petroleum ether. Finally our group was able to determine the Rf value of benzophenone and we found out that it has an Rf value of 0.4737 so this would mean that benzophenone is non-polar because its Rf value is near to 1.
it is used as an anti-atherosclerotic agent and also in the manufacture of dyes and perfumes.
