Heterogeneous Palladium-Catalyzed Synthesis of Aromatic Ethers by Solvent-Free Dehydrogenative Aromatization: Mechanism, Scope, and Limitations Under Aerobic and Non-Aerobic Conditions
derivatives and alcohols, both non-aromatic precursors, aryl ethers could be synthesized in good yields and with good selectivities in the presence of a catalytic amount of Pd/C, in one step, without added solvent, in a reaction vessel open to air. For less reactive substrates, the addition of 1-octene in a closed system undernon-aerobicconditions improved the conversion. In addition, the catalyst could
The present invention relates to a fragrance composition to be incorporated within core shell capsules preferably formaldehyde melamine and optionally urea capsules in order to reduce fragrance leakage from the capsules on storage in liquid, gel and soft solid household, laundry and personal care products and cosmetics which contain surfactants and/or solvents.
The fragrance composition of the invention comprises:
I) 60-100% by weight of at least 5 fragrance compounds fragrance compounds. 20-100% by weight of said fragrance compounds being comprised of at least 3 compounds having a molecular weight less than 325 atomic mass units.
The present disclosure discloses a novel microcapsule which is endowed for example with reduced leakage of encapsulated materials. The microcapsule contains one or more fragrances and is suitable for inclusion in non-edible consumer goods products, laundry products, personal care products and cosmetic products. The microcapsule can be obtained in an economic and efficient manner by polymerizing an emulsion so that emulsion droplets are encapsulated into a subsequently cured polymeric shell.
