  2. Chlorobenzene - Wikipedia

    en.wikipedia.org/wiki/Chlorobenzene

    At one time, chlorobenzene was the main precursor for the manufacture of phenol: [10] C 6 H 5 Cl + NaOH → C 6 H 5 OH + NaCl The reaction is known as the Dow process , with the reaction carried out at 350 °C using fused sodium hydroxide without solvent.

  3. Sodium phenoxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_phenoxide

    Sodium phenoxide is a moderately strong base. Acidification gives phenol: [5] PhOH ⇌ PhO − + H + (K = 10 −10) The acid-base behavior is complicated by homoassociation, reflecting the association of phenol and phenoxide. [6] Sodium phenoxide reacts with alkylating agents to afford alkyl phenyl ethers: [2]

    The simplest is phenol, C 6 H 5 OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. Phenol – the simplest of the phenols Chemical structure of salicylic acid, the active metabolite of aspirin. Phenols are both synthesized industrially and produced by plants and ...

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  9. Free-radical halogenation - Wikipedia

    en.wikipedia.org/wiki/Free-radical_halogenation

    The relative rates at which different halogens react vary considerably: [citation needed] fluorine (108) > chlorine (1) > bromine (7 × 10 −11) > iodine (2 × 10 −22).. Radical fluorination with the pure element is difficult to control and highly exothermic; care must be taken to prevent an explosion or a runaway reaction.
