摘　　要：以L-2-丙氨酸为原料,用水做溶剂,在5%Ru/C纳米催化剂作用下,催化加氢还原得到L-2-氨基丙醇,优化的工艺参数为:L-2-丙氨酸水溶液的浓度为15%,50%的磷酸水溶液作为助剂,氢气压力为5.5 MPa,在100℃下反应12 h,收率为85%,光学纯度为99%以上。L-2-amino-l-propanol was obtained by reduction of L-2-alanine using 5% Ru/C as catalyst and water as solvent. The optimized conditions were as the following： the concentration of L-2-alanine was 15%, 50% phosphoric acid was used as assistant, the pressure of hydrogen gas was 5.5 MPa, the yield was 85% and optical purity was 99% reacting at 100 ℃ for 12 h.
