摘　　要：用封锁酸(碱)性位点的方法,研究了La2O3/γ-Al2O3的酸碱性对肉桂醛MPV反应还原为肉桂醇的影响。结果表明,La2O3/γ-Al2O3的酸性和碱性位点均对肉桂醛MPV反应有影响,而催化剂酸性位点对反应的影响大于碱性位点。The effects of acid/base sites character of La203/γ-Al203 catalysts on Meerwein-Ponndorf- Verley（MPV） reduction of cinnamaldehyde to cinnamyl acohol were investigated by blockading the acid/ base sites on the catalysts. The experimental results showed that the acid and base sites of the catalysts had influence on the reaction and the influence of acid sites on the reaction was larger than that of base sites.
