Method and catalysts for obtaining unsaturated alpha-beta carbonylic compounds used in the perfume and scent industry |
摘要 |
The invention describes the preparation of unsaturated alpha , beta carbonylic compounds, more specifically structure (I) unsaturated alpha , beta ketones and structure (II) aldehydes. (DIAGRAM 1) by mixed aldolic condensation between an alkyl or alkenyl aldehyde and an aldehyde or ketone using heterogeneous catalysts having basic characteristics. The resulting carbonylic compounds exhibit scent and may be used directly as essences or are precursors of essences commonly used in perfumes. |
