摘要:
The present application relates to perfume raw materials, perfume delivery systems and consumer products comprising such perfume raw materials and/or such perfume delivery systems, as well as processes for making and using such perfume raw materials, perfume delivery systems and consumer products, wherein the perfume raw material is 3-((1R, 5S)-6,6-dimethylbicyclo[3.1.1]hept-2-en-2yl)-2,2-dimethylpropanal. Such perfume raw materials and compositions, including the delivery systems, disclosed herein expand the perfume communities' options as such perfume raw materials can provide variations on character and such compositions can provide desired odor profiles.
摘要:
The present invention relates to the field of catalytic hydrogenation and, more particularly, to a process for the reduction by hydrogenation, using molecular H 2 , of a C 6 -C 20 conjugated dienal into the corresponding deconjugated enal, characterized in that said process is carried out in the presence of a catalytic system comprising at least a base and at least one complex in the form of a rhodium complex comprising a C 34 -C 60 bidentate diphosphine ligand (L2) coordinating the rhodium.
摘要:
Compounds, compositions, and methods for controlling an arthropod pest population that employ an eremophilane sesquiterpene parent structure are presented. The compounds have minimal adverse or toxic effects on humans, non-human animals, and the natural environment. The compounds may be isolated from natural sources, semi-synthesized from naturally occurring compounds, or completely synthesized. The compounds may be applied directly to a pest, or the locus of a pest, and function as topical or ingestible toxins. Eremophilane sesquiterpenes 13-hydroxy-valencene, valencene-11,12-epoxide, valencene-13-aldehyde, and nootkatone-1,10-11,12-diepoxide are exemplary compounds.
摘要:
Processes for producing β-hydroxy-ketones and a,β-unsaturated ketones are disclosed which comprise the crossed condensation of an aldehyde with a ketone in the presence of a hydroxide or aikoxide of aikali metal or an aikaline earth metal as catalyst. The products of the process, β-hydroxyketones and a,β-unsaturated ketones, are useful for the preparation of many commercially important products in the chemical process industries including solvents, drug intermediates, flavors and fragrances, other specialty chemical intermediates.

摘要:
The invention relates to compounds of the general formula wherein R 1 to R 3 and R 6 are H, methyl or ethyl, R 4 is methyl or ethyl, or R 1 +R 2 form -C(H 2 ) n -, with n being 3 or 4 and the use of these compounds as an odorant or as an ingredient of an odorant composition.
摘要:
The invention concerns carbonyl compounds of general formula (Ia) and/or (Ib). The carbonyl compounds are characterized by interesting fragrance qualities which are effective over a wide area and are suitable as fragrances, for example, in cosmetic preparations, technical products or alcohol-based perfumes.
