  Catalytic oxidation of limonene over zeolite-Y entrapped oxovanadium (IV) complexes as heterogeneous catalysts

  摘要：

  A series of VO(IV) complexes with Schiff base ligands derived from vanillin thiophene-2-carboxylic hydrazone (VTCH), vanillin furoic-2-carboxylic hydrazone (VFCH), salicylaldehyde thiophene-2-carboxylic hydrazone (H2STCH) and/or salicylaldehyde furoic-2-carboxylic hydrazone (H2SFCH) have been synthesized as neat and their entrapped complexes into the nanopores of zeolite-Y. These materials were characterized by several techniques: chemical analysis (ICP-OES and elemental) and spectroscopic methods (FT-IR, electronic, XRD, SEMs and BET). All the prepared catalysts were tested over the liquid phase limonene oxidation reaction, using t-butyl hydroperoxide (TBHP) and/or 30% H2O2 as oxidants. Limonene glycol, carveol and carvone were the main products obtained. It was observed that zeolite-Y based entrapped complexes exhibited higher catalytic activity than neat VO(IV) complexes. These zeolite-Y based entrapped complexes are stable and recyclable under current reaction conditions. Amongst them, [VO(VTCH)(2)]-Y showed higher catalytic activity (97.7%) with limonene glycol (45.1%), selectivity. (C) 2014 Elsevier B.V. All rights reserved.

  The present invention relates to a delivery system in the form of a dynamic mixture obtained by reacting together, in the presence of water, at least one hydrazine derivative with at least one perfuming, flavoring, insect repellent or attractant, bactericide or fungicide aldehyde or ketone. The inventive mixture is capable of releasing in a controlled and prolonged manner the aldehyde or ketone in the surrounding environment. Furthermore, the present invention concerns also the use of these dynamic mixtures as perfuming ingredients as well as the perfuming compositions or perfumed articles that include such mixtures.

  本发明涉及一种以动态混合物形式呈现的传递系统，所述混合物是通过在水的存在下将至少一种肼衍生物与至少一种香料、调味剂、驱虫剂或诱引剂、杀菌剂或杀真菌剂醛或酮反应而得到的。该创新混合物能够以受控和延长的方式释放周围环境中的醛或酮。此外，本发明还涉及将这些动态混合物用作香料成分，以及包括这种混合物的香料组合物或带香物品的使用。
