    摘要： The present invention relates to a method of working up an aluminium-containing reaction product from the production of isopulegol by cyclization of citronellal in the presence of complex compounds, comprising at least one ligand of the formula (I), where Ar1, Ar2, Ar3, Ar4 are chosen from C6-C15-aryl or C2-C15-hetero; R1, R2, R3, R4 are chosen from H, C1-C6-alkyl, C1-C6-perfluoroalkyl, C1-C6-alkoxy, C7-C12-aralkyl, halogen, SiR5bR6bR7b, C6-C10-aryl, NR8bR9b, SR10b, NO2; and where R1 or R2 and/or R3 or R4, together with A, can form an aromatic or nonaromatic cycle; etc.; in which a) the aluminum-containing reaction product is subjected to distillative separation, b) the isopulegol-depleted bottom product is brought into close contact with an aqueous base and c) the ligand of the formula (I) is separated off from the organic phase, preferably by crystallization. Moreover, the invention relates to a method of producing isopulegol, and to a method of producing menthol.
