Aniline doesn't react with sodium hydroxide.
In o-aniline phenol Intramolecular hydrogen bonding occurs which is not possible in meta and is responsible for less solubility
There is no any such difference between Aniline point and mixed Aniline point . . . . .
The aniline point of kerosene is 60-69 oC.
no aromtics show the low aniline point....because higher the aniline point higher the pariffinic content and lower the aromatic content
aniline point is the lowest temp in f in wich equal volume of aniline and dieasel are completely missble. Poling point is that temp in which aromatic compounds are not freezed
no
To improve the aniline point of oils, one can fractionate the oil to remove lighter components, adjust the chemical composition to increase the aromatic content, or add specific additives that can raise the aniline point. Additionally, removing any contaminants or impurities that can lower the aniline point can also help improve it.

Aniline can be estimated using acid-base titration. In this process, a known concentration of acid is added to a solution containing aniline until the equivalence point is reached, indicated by a color change due to the formation of a salt. This helps in determining the concentration of aniline present in the solution.
Aniline derivatives typically produce a reddish tint in hair. To identify if a hair dye contains an aniline derivative, you can check the ingredient list for common derivatives like p-phenylenediamine (PPD) or related compounds. A patch test can also help determine if the hair dye contains an aniline derivative and if it may cause a reaction.
The specific test for pentoses is the Bial's test. This test involves heating the sugar with orcinol and an acidic solution, resulting in a blue-green color if pentoses are present.
Aniline has a higher boiling point than phenol because aniline can form strong hydrogen bonds due to the presence of an amino group. Phenol has a higher boiling point than toluene because phenol molecules can form intermolecular hydrogen bonds because of the hydroxyl group. Toluene has a higher boiling point than benzene due to the presence of a bulky methyl group which increases Van der Waals forces between toluene molecules.
