摘 要:以氯苯、環(huán)己烯、乙酰氯為原料,通過(guò)Friedel-Crafts 反應、Baeyer-Villiger反應、水解反應得到4-(4-氯苯基)環(huán)己醇。通過(guò)正交試驗得到Friedel-Crafts 反應和Baeyer-Villiger反應優(yōu)化后的工藝條件。4-(4-氯苯基)環(huán)己醇總收率達12.9%,較文獻收率提高了6%以上。所得醇經(jīng)次氯酸鈉氧化,得到4-(4-氯苯基)環(huán)己酮,氧化收率87%,產(chǎn)品的結構經(jīng)1H NMR、GC-MS鑒定。 |

Abstract:4-(4-Chlorophenyl)cyclohexanol was synthesized from chlorobenzene,cyclohexene and acetyl chloride via Friedel-Crafts reation,Baeyer-Villiger reaction ,hydrolysis. By experiments utilizing an orthogonal design,optimum synthesis conditions of Friedel-Crafts reation and Baeyer-Villiger reaction were obtained. The total yield of 4-(4-chlorophenyl)cyclohexanol is 12.9%,which is 6% higher than the literature. 4-(4-chlorophenyl)cyclohexanol was oxidated with NaClO to give 4-(4-chlorophenyl)cyclohexanone with yield of 87%. This is a new synthesis route for 4-(4-chlorophenyl)cyclohexanone. The products were identified by 1H NMR,GC-MS. |
Key words:4-(4-chlorophenyl)cyclohexanol;4-(4-chlorophenyl)cyclohexanone;synthesis. |
