METHOD FOR THE SEPARATION OF HYDROXYACETONE FROM HYDROXYACETON CONTAINING PHENOL

The method is materialized by reduced energy amount in the separation of the hydroxyacetone, by limiting the phenol losses. It is used for the separation of hydroxyacetone from phenol-containing hydroxyacetone which is produced in acidic catalytic degradation of cumenehydroperoxide by the steam-like...

Zusammenfassung:	The method is materialized by reduced energy amount in the separation of the hydroxyacetone, by limiting the phenol losses. It is used for the separation of hydroxyacetone from phenol-containing hydroxyacetone which is produced in acidic catalytic degradation of cumenehydroperoxide by the steam-like phenol-containing hydroxyacetone with a base. Combination is made between a distillation and reaction column when either the steam-like phase taken from the head of the distillation column is fed to a reactor where it reacts with the base, or the reaction takes place in a distillation column which is supplied not only with the distilled phenol-containing hydroxyacetone but also with the base. The method can also be applied in the flotation of the raw phenol removed as waste in the Hawk's synthesis. 10 claims, 3 figures
