FIELD: chemistry.SUBSTANCE: invention relates to a method of producing geranial, which is used in perfumery as flavouring agents and perfumes, of a mixture of isomers geranial and neral (citral). Method is based on carrying out transformations citral in the presence of acid catalysts, preferably, Montmorillonite clay, leading to preferred expenditure neral by formation of oligomers, and indent geranial′ unaffected. Separation of geranial from the reaction mixture can be performed column chromatography or by distillation at low pressure.EFFECT: proposed method allows to obtain an end product using simple and efficient technology on the basis of available and cheap citral.1 cl, 5 ex |
