【Abstract】 Cyclohexanone is condensed in the prosence of acid or alkalis as a catalyst to form 2 (1 cyclohexenyl)cyclohexanone(Ⅰ), 2 cyclohexylidene cyclohexanone(Ⅱ) and some other side products. Both Ⅰ and Ⅱ are important intermediate for the synthesis of substituted phenols. The condensation on different condition catalyzed by acid or alkalis are discussed in detail.更多还原
