The value gives an approximation for the content of aromatic compounds in the oil, [2] since the miscibility of aniline, which is also an aromatic compound suggests the presence of similar (i.e. aromatic) compounds in the oil. The lower the aniline point, the greater is the content of aromatic compounds in the oil.
Aniline absorbs in the K (220 - 250 nm) and the B (250 - 290 nm) bands exhibited by benzenoid compounds. The K and B bands arise from π to π* transitions as a result of the a group containing multiple bond being attached to the benzene ring. When dissolved in ethanol, λ max for aniline is 230 nm, but in dilute aqueous acid λ max is 203 nm ...
Melting point: 162 to 164 °C (324 to 327 °F; 435 to 437 K) ... Commercially available, it may be prepared by treating benzoic acid with aniline. [1] References
Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2.Consisting of a phenyl group (−C 6 H 5) attached to an amino group (−NH 2), aniline is the simplest aromatic amine.
Benzoic acid and its salts are used as food preservatives, represented by the E numbers E210, E211, E212, and E213. Benzoic acid inhibits the growth of mold, yeast [23] and some bacteria. It is either added directly or created from reactions with its sodium, potassium, or calcium salt. The mechanism starts with the absorption of benzoic acid ...
The exact composition of the foam is unclear, but the process is believed to involve acidic protonation as well as displacement of the amine group by a sulfonic acid moiety. [ 10 ] In Carbon snake demo, paranitroaniline can be used instead of sugar, if the experiment is allowed to proceed under an obligatory fumehood . [ 11 ]
Diphenylamine is an organic compound with the formula (C 6 H 5) 2 NH. The compound is a derivative of aniline, consisting of an amine bound to two phenyl groups. The compound is a colorless solid, but commercial samples are often yellow due to oxidized impurities. [5]
Benzyl alcohol is subsequently metabolized to benzoic acid. The conjugates of benzoic acid ( hippuric acid and the glucuronide of benzoic acid) are rapidly eliminated in urine. [ 1 ] When given in large doses to laboratory animals, benzyl benzoate can cause hyperexcitation, loss of coordination, ataxia , convulsions , and respiratory paralysis .
