Reaktionsschritte

The process described in Japanese Patent Laid-Open Publication No. 59742/1992, however, has a problem of using expensive alicyclic diol. If 2,2-bis(4-hydroxyphenyl)propane that is relatively inexpensive is used as a starting material, reactions of two steps, namely, hydrogenation reaction of 2,2-bis(4-hydroxyphenyl)propane and oxidation reaction of 2,2-bis(4-hydroxycyclohexyl)propane obtained by the hydrogenation reaction, must be conducted to produce 2,2-bis(4-oxocyclohexyl)propane, so that the process becomes complicated.
