摘要
研究了红花油在密闭容器中微波辐射条件下,使用甲酸铵溶液作为载氢体、钯/碳作为催化剂的催化转移氢化(CTH)。与其他的催化转移氢化相比,该方法能比较好地将亚油酸完全转化成单不饱和脂肪酸,硬脂酸稍有增加。不用乳化剂或添加大量的水,使用微波CTH就具有选择性。
Catalytic transfer hydrogenation (CTH) of safflower oil was studied using aqueous ammonium formate as hydrogen donor and palladium on carbon as catalyst in a closed vessel under controlled microwave irradiation conditions. The method offered good selectivity in complete reduction of linoleic acid to monounsaturated acid with a slight increase in stearic acid compared to other reported catalytic transfer hydrogenation methods. Selectivity was achieved by using microwave-assisted CTH with neither emulsifier nor high ratio of water to oil.
