Process for the isolation of dodecatrienal and its use as aroma substance
Abstract:
The present invention relates to a process for preparing at least one compound with Z−1 cycles and 7 to 16 carbon atoms with at least one aldehyde group, at least comprising the stages: (a1) oxidation of a composition (A), at least comprising a cyclic olefin with Z cycles and 7 to 16 carbon atoms and at least two C—C double bonds, by means of dinitrogen monoxide to give a composition (A1), (a2) separating off the at least one cyclic olefin with Z cycles and 7 to 16 carbon atoms with at least two C—C double bonds from the composition (A1) from stage (a1) in order to obtain a composition (A2), (b1) separating off the at least one cyclic compound with Z cycles and 7 to 16 carbon atoms with a keto group from the composition (A2) from step (a2), in order to obtain a composition (B1), comprising at least 50% by weight of the at least one compound with Z−1 cycles and 7 to 16 carbon atoms with at least one aldehyde group and at least two C—C double bonds, where Z may be 1, 2, 3 or 4.
Abstract(Chinese):

本发明涉及至少一种具有Z-1个循环和7-16个碳原子的化合物与至少一个醛基的制备方法，至少包括以下步骤：（a1）组合物（A）的氧化，至少 包含具有Z循环和7至16个碳原子的环烯烃以及至少两个C-C双键的方法，借助于一氧化二氮，得到组合物（A1），（a2）以Z循环分离出至少一种环状烯烃 和从碳（a1）组合物（A1）至少具有两个C-C双键的碳原子数为7〜16的碳原子，以获得组合物（A2），（b1）以Z循环分离出至少一种环状化合物 和具有来自步骤（a2）的组合物（A2）的酮基的7至16个碳原子，以获得组合物（B1），其包含至少50重量％的至少一种Z-1循环的化合物 和具有至少一个醛基和至少两个C-C双键的7至16个碳原子，其中Z可以是1,2,3或4。
