| abstract | 1 Method of isolating phenol, obtainednby the cumene method from a neutralized decomposition mixturenaqueous sodium phenate solution and / ornsodium hydroxide by its distillative separationnper phenol fraction 1 acetone fraction and fraction distillationnphenolic, characterized in that of the decomposing mixturen, neutralized to pH 7.5-8.5, the salts are extractednthe water phase of the distillate from the azeotropic distillation column,nthen, after being obtained from the mixture, knownnby distillation, phenol fraction 1 after separationnphenol, also known by the method throughnsubjected to distillation, from higher-boiling martyrdomsnit undergoes azeotropic distillation to give off a lower boilingnimpurities, but as column refluxnthe condensate formed in steam nipples is usednduring the hydroperoxide concentration operationncumene and the distillate obtained is completely withdrawnnoutside the column layout, the water phase being heterogeneousnthe distillate is used for extractionnsalt from the decomposition mixture, and phenol, obtained fromnbottom of this column goes directly to the bednstrongly acidic, macroporous location and surrendernit in the known way of catalytic and final refiningn&nrectification. |
