Reaction of phenol with ammonia
WebThe odor threshold for phenol is 0.04 parts per million (ppm), with a strong very sweet odor reported. (1,7) Phenol is very soluble in water and is quite flammable. (2) The chemical formula for phenol is C 6 H 6 O and the molecular weight is 94.1 g/mol. (8,9) The vapor pressure for phenol is 0.3513 mm Hg at 25 °C, and it has a log octanol ... WebThe reagent lacks sensitivity in situations where there may be amines as well as ammonia, however this can be overcome in part by the use of 2-phenylphenol to replace phenol. An ion selective electrode, or distillation/titration method can often be used in cases where Berthelot chemistry is ineffective.

WebJun 14, 2024 · Phenol is first deprotonated by the sodium hydroxide as you already thought. The deprotonation of Phenol is favored because the pKa of Phenol is lower than the pKa of water meaning $\ce{OH-}$ is a stronger conjugated base than $\ce{PhO-}$: The formed Phenolate is a good nucleophile, and will attack the methyl groups of the Dimethyl Sulfate.
