    • Provided is a method of producing lavandulal at a high yield by controlling formation of its isomer of lavandulal as a by-product.In a method of producing lavandulal by making an acetal compound represented by the following formula (I) react with 3-methyl-1-butene-3-ol in the presence of an acid catalyst, the method includes: adding, to a liquid mixture comprising an acid catalyst, an acetal compound represented by the following formula (I), and 3-methyl-1-butene-3-ol in at least a portion of an amount to be used (3-methyl-1-butene-3-ol (a)), 3-methyl-1-butene-3-ol in the other portion of the amount to be used (3-methyl-1-butene-3-ol (b)); and maintaining the liquid mixture at a temperature of 110° C. or higher: in which Each R in the formula (I) represents an alkyl group.
    • 本发明提供通过控制其作为副产物形成薰衣草的异构体而以高产率生产薰衣草的方法。 通过使下式(I)表示的缩醛化合物在酸催化剂的存在下与3-甲基-1-丁烯-3-醇反应来制造薰衣草的方法包括:向液体混合物 包括酸催化剂,由下式(I)表示的缩醛化合物和至少一部分用量的3-甲基-1-丁烯-3-醇(3-甲基-1-丁烯-3 (3-甲基-1-丁烯-3-醇(b))的另一部分中的3-甲基-1-丁烯-3-醇。 并将液体混合物保持在110℃或更高的温度:其中式(I)中的每个R表示烷基。
