FIELD: chemistry.

SUBSTANCE: invention refers to the way of production of phenol, acetone and α-methylsterene, and to the installation for its implementation. The way consists in decompounding of cumene hydroperoxide and dimethylphenyl carbinol that are included into the technical cumene hydroperoxide, in the solvent with the presence of heterogeneous catalyst by means of catalytical distillation in the continuous isothermal mode at the boiling point of the solvent and with the latter's recirculation; as a solid heterogeneous catalyst, heteropoly acid H₃PW₁₂O₄₀ or caesium-displaced salt of heteropoly acid Cs_2.5H_0.5PW₁₂O₄₀ is applied on the silicon dioxide, and as a solvent, acetone is employed. As a bearer, mesoporous silicon dioxide of MCM-41 grade is used, and decompounding of the cumene hydroperoxide and dimethylphenyl carbinol is carried out in two stages; the first stage stipulates decompounding of cumene hydroperoxide thus releasing phenol and acetone, and the second one - of dimethylphenyl carbinol thus releasing a-methylsterene; the mesoporous silicon dioxide and heteropoly acid or caesium-displaced salt of the heteropoly acid are used with the following component ratio, weight %: heteropoly acid - 10-50; silicon dioxide - the rest; or caesium-displaced salt of the heteropoly acid - 10-20; silicon dioxide - the rest.

EFFECT: decompounding of the cumene hydroperoxide and dimethylphenyl carbinol with 100 % conversion and 100 % selectance.
