分离十二碳三烯醛的方法及其作为香料的用途
摘要：
本发明涉及一种制备至少一种具有Z-1个环和7-16个碳原子并具有至少一个醛基的化合物的方法，所述方法至少包括以下步骤：(a1)使用一氧化二氮将至少包含具有Z个环和7-16个碳原子和至少两个C-C双键的环状烯烃的组合物(A)氧化，以获得组合物(A1)，(a2)从来自步骤(a1)的组合物(A1)中分离出所述至少一种具有Z个环和7-16个碳原子并具有至少两个C-C双键的环状烯烃，以获得组合物(A2)，和(b1)从来自步骤(a2)的组合物(A2)中分离出具有Z个环和7-16个碳原子并具有一个酮基的环状化合物，以获得组合物(B1)，该组合物(B1)包含至少50重量％具有Z-1个环和7-16个碳原子并具有至少一个醛基和至少两个C-C双键的化合物。根据本发明，Z可为1、2、3或4。
摘要（英）：

The invention relates to a method for producing at least one compound with Z-1 cycles and between 7 and 16 C atoms with at least one aldehyde group, said method comprising at least the following steps: (a1) oxidation of a composition (A), at least containing one cyclic olefin with Z cycles and between 7 and 16 C atoms and at least two C-C double bonds, using dinitrogen monoxide, to obtain a composition (A1), (a2) isolation of the at least one cyclic olefin comprising Z cycles and between 7 and 16 C atoms with at least two C-C double bonds from the composition (A1) from stage (a1), to obtain a composition (A2), and (b1) isolation of the cyclic compound or compounds with Z cycles and between 7 and 16 C atoms with a keto group from composition (A2) in step (a2), to obtain a composition (B1); containing at least 50 wt % of the compound or compounds with Z-1 cycles and between 7 and 16 C atoms with at least one aldehyde group and at least two C-C double bonds. According to the invention, Z can be 1, 2, 3 or 4.
