氢化大豆卵磷脂Pd/C催化剂制备工艺优化（Preparation Process Optimization of Pd/C Catalysts for Hydrogenation Soy Lecithin）
大豆卵磷脂 氢化 Pd/C催化剂 制备
2010/12/28
应用浸渍法制备Pd/C催化剂，以大豆卵磷脂氢化反应前后碘值的变化作为指标，考察了制备条件对Pd/C活性的影响，并借助透射电镜的表征手段分析催化剂的形貌变化。结果表明，制备大豆卵磷脂氢化Pd/C催化剂的优化工艺为：原料炭经10%硝酸预处理后，在40℃的3.5mg/mL H2PdCl4溶液中浸渍2h，在30%甲醛、还原温度80℃、pH值1～2的条件下还原5h，并经80℃真空干燥获得成品。催化剂P...
