<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing, in an industrially advantageous manner, a bisphenol derivative possessing a cyclic hydrocarbon where the number of ring constituent members of a cyclic ketone is at least 7 without using a highly corrosive hydrogen chloride gas requiring a special facility.SOLUTION: After sulfuric acid and/or sulfonic acid, phenol, a cyclic ketone expressed by the following formula (1): [chemical 1] (in the formula, n is an integer of 1 to 8), and a thiol have each been homogenized, the reaction mass is statically placed in a partially or entirely solidified state at or below 40°C, which is lower than the melting point of the phenol (40.5°C), so as to conclude the reaction, and a bisphenol derivative possessing a cyclic hydrocarbon where the number of ring constituent members of a cyclic ketone is at least 7 is obtained.</p> |
