The kinetics of catalytic transfer hydrogenation (CTH) of low-erucic-acid rapeseed oil using ammonium formate as a hydrogen donor over a Ni-Ag/SBA15 catalyst were studied. Then, a kinetic model for the hydrogenation of low-erucic-acid rapeseed oil was established, and it was found that the reaction rate constants of hydrogenations of 9c-18:1 and 12c-18:1 oleic acid were 0.1262 and 0.0148, and the catalytic selectivity of linoleic acid was 2.04. For the catalyst loading of 0.23%, the hydrogenation temperature was 80°C, the ammonium formate concentration was 0.32 mol/50 mL, and the low-erucic-acid rapeseed oil was hydrogenated in 90 min; it was also found that the iodine value of low-erucic-acid rapeseed oil was 80 g I/100 g, the oleic acid content was 65%, and the trans fatty acids (TFAs) content was only 6.7%. Therefore, CTH may be widely used in the modification of oils and fats.
研究了以甲酸铵为氢供体，在Ni-Ag/SBA15催化剂上进行低芥酸菜籽油催化转移氢化（CTH）的动力学。然后，建立了低芥酸菜籽油氢化的动力学模型，发现9c-18:1和12c-18:1油酸氢化的反应速率常数分别为0.1262和0.0148，亚油酸的催化选择性为2.04。在催化剂负载量为0.23%、氢化温度为80℃、甲酸铵浓度为0.32 mol/50 mL的条件下，低芥酸菜籽油在90 min内完成氢化；还发现低芥酸菜籽油的碘值为80 g I/100 g，油酸含量为65%，反式脂肪酸（TFA）含量仅为6.7%。因此，催化转移氢化可能广泛应用于油脂改性。
