As intermediates in organic synthesis, used to prepare cinnamon chloride, is used to prepare long-acting antagonist of the brain function of vascular contraction of the excellent benefits hydrochloride raw material, while cinnamon chloride can also be used for synthesis of microbial drug resistance derived for naphthalene Finland and anticancer drugs toremifene. flunarizine dihydrochloride is a calcium antagonist, can also be used to synthesize cinnamic chloride. cinnamyl alcohol is used to prepare spices Gui Gui acid ester materials.
1 share benzyl alcohol were added to 0.01 share aluminum powder, heated to 60 ℃ reaction to release hydrogen, the temperature rises to 180 ℃, to stop the release of hydrogen so far. Benzyl alcohol solution of aluminum cooled and filtered, then added to a mixture of benzyl alcohol and cinnamaldehyde (quality 1:1). Conditions in the 0.0027MPa heated to boiling, and the reflux ratio at 80 ℃ under 3 to 4 the reaction of steam out of benzaldehyde, benzyl alcohol while additional. Until the theoretical amount of steam out of benzaldehyde of 95% after the stop feeding, and steamed out of the remaining benzyl alcohol, cinnamic alcohol and then distilled out of crude. And then by vacuum distillation, collecting 117 ℃ (7kPa) fractions, namely cinnamyl alcohol.
