Type of chemical reaction from cinnamaldehyde using nickel-tin intermetallics under mild conditions

摘要

Ni_3Sn, Ni_3Sn_2, and Ni_3Sn_4 intermetallics were synthesized via mechanical alloying with different contents of nickel and tin, 43, 58, 73% of tin contents, respectively. These intermetallics were characterized by XRD and SEM-EDX. As catalysts, the activity of Ni_xSn_y intermatallics was studied in term of chemical reactions using cinnamaldehyde. Moreover, formic acid was considered to be used as a hydride donor and also as a co-catalyst in order to obtain cinnamyl alcohol. In this work, the optimal time, temperature, amount and type of Ni_xSn_y intermetallics, and also amount of formic acid were investigated. Ni_3Sn_4 had the highest turnover number. The final products of cinnamyl alcohol, hydrocinnamaldehyde, cinnamic acid, and benzaldehyde detected by GC-FID were obtained.
