FIELD: industrial organic synthesis.
SUBSTANCE: invention relates to joint phenol-acetone production via selective decomposition of cumene hydroperoxide. Process is conducted in several in series connected reactors constructed in the form of shell-and-tube heat-exchangers, wherein part of decomposition product is recycled into reaction zone and mixed with feed stream to be decomposed, weight ratio of recycled stream to feed stream being less than 10. Reactors with tubular hydrodynamic characteristic have volumetric heat-exchange surface equal to or larger than 500 m2/m3. Preferably, residual concentration of cumene hydroperoxide is 0.1-0.3 wt % and its residence time in decomposition zone ranges from 0.5 to 10 min.
EFFECT: increased selectivity of decomposition at lesser recycle apparatus volume and reduced investment expenses.
