Abstract
We report that catalytic quantities of the Lewis acidic metal catalysts scandium triflate and bismuth triflate promote conversion of oleic, linoleic, palmitic and myristic acids and their glyceryl triesters to the corresponding methyl esters (biodiesel) in greater than 90% yield upon microwave heating. Additionally, both catalysts could be recovered and reused in esterification reactions at least six times.
摘要
我们报告称，路易斯酸性金属催化剂三氟甲磺酸钪和三氟甲磺酸铋在微波加热下，以催化量促进油酸、亚油酸、棕榈酸和肉豆蔻酸及其甘油三酯转化为相应的甲酯（生物柴油），产率大于 90%。此外，这两种催化剂在酯化反应中至少可以回收和重复使用六次。
