| titleOfInvention | Method for producing phenols |
| abstract | A method for producing phenols having an excellent effect of improving the liquid separation property between an oil layer and an aqueous layer in a water washing step, and thus being able to be carried out with high productivity. The hydroperoxide concentration in Extract-2, which includes the following steps and is subjected to a water washing step, is 20% by weight or less. Oxidation step: Oxidation raw material liquid containing alkylbenzene is oxidized with oxygen or air to obtain an oxidation reaction liquid containing hydroperoxide. Alkaline extraction process: Extraction liquid-1 containing hydroperoxide by extracting the oxidation reaction liquid with an alkaline aqueous solution Solvent extraction step: Extraction solution-1 obtained in the alkali extraction step is extracted with an organic solvent to obtain an extraction solution-2 containing hydroperoxide. Water washing step: Extraction solution-2 obtained in the solvent extraction step is washed with water , To obtain an oil layer containing hydroperoxide with low alkali content Acid decomposition process: Acid decomposition of the hydroperoxide contained in the oil layer obtained in the water washing process to obtain phenols |
