Phenolic Production Method |
| abstract |
The present invention relates to a phenol production method comprising the following steps:n n n a) oxidizing cumene to form an oxidation product comprising cumene hydroperoxide;n n n b) decomposing the oxidation product using an acidic catalyst to form a decomposition product comprising phenol, acetone and impurities;n n n c) neutralizing and washing the degradation product with a basic aqueous medium to obtain a neutralized degradation product;n n n d) separating the neutralized degradation product by at least one distillation step into at least one phenol containing fraction and one aqueous fraction comprising hydroxyacetone;n n n e) treating said aqueous fraction with an oxidizing agent in the presence of a base to obtain a reduced basic aqueous medium in hydroxyacetone;n n n f) refeeding at least a portion of said basic aqueous medium to said neutralizing and washing step c);n n n g) recovering phenol from the phenol containing fractions obtained in step d). |
