Method for separating phenol from aqueous solution of high concentration phenol

摘要

The present invention relates to a method for separating phenol from an aqueous solution of high concentration phenol. More particularly, the present invention relates to a method for economically separating and purifying phenol by a simple process by adding carbon dioxide to a high concentration phenol aqueous solution to form a clathrate. According to the present invention, it is possible to separate phenol from a high-concentration aqueous phenol solution without any additional solvent and a subsequent step, and the method of separating phenol according to the present invention can prevent additional energy consumption since the temperature required for separation is lower than room temperature It is economical and it has been confirmed that a high concentration of phenol can be separated and purified by 100 mol% of phenol solids and 0.6 mol% of phenol aqueous solution by one step process.
