Abstract: In order to make high yield cispinane,the reaction of hydrogenation from pinene to pinane was studied,in which two series of Raney Ni prepared from two different alloy materials,different reaction temperatures,hydrogen pressures,solvents.Purities of pinene made up of αpinene and βpinene,and dosage of catalysts were taken into consideration.As a result,a kind of Raney Ni of ideal activity and selectivity in pinene hydrogenation was determined.Based on hydrogenation experiments,the reaction condition of pinene hydrogenation was optimized.The optimum parameters on how to get high yield cispinane in pinene hydrogenation were determined as follows:(1)the reaction temperature was 100 ℃;(2)the hydrogen pressure was 6.0 MPa;(3)the solvent was nbutanol;(4)the purity of αpinene in raw material of pinene was at least 85%;(5)the dosage of the catalyzer was 3%.Under such conditions above mentioned,the transportation of pinane from pinene was nearly 100%,and the final yield of cispinane could be maintained more than 95%.
