Synthesis of α,α-diphenyl-4-piperidinomethanol by catalytic Hydrogenation
JIANG Chong-wen; He De-wen(School of Chemistry and Chemical Engineering of Central South University; Changsha 410083; China)
Abstract:A novel technology of hydrogenation for synthesizing the α, α-diphenyl-4-piperidinomethanol was proposed by using Pt/C catalyst. The effects of solvents, pressure, temperature, catalyst amount and reaction time on the yield were investigated. Under the optimum reaction condition, the result showed that the yield can reach 92.4% and the purity was up to 98.8%.
Key words:catalytic hydrogenation; α; α-diphenyl-4-piperidinomethanol; synthesis
