发明人:JAUNKY PIOTR; MANE JEAN; SCHROEDER MARTIN
权利人:MANE FILS V
摘要:A compound of general formula (I) with or without the double bond illustrated by the dotted line. In formula (I), X is a CHO, CH2OH, CH2OC(O)R or CH(OR)2 group, and R represents a linear or branched C1-C5 alkyl or alkenyl chain. The synthesis method for the compound, and especially the 6,8-dimethyl-non-7-enal (1) prepared by the hydroformylation of the 5,7-dimethyl-octa-1,6-diene is also disclosed, as well as compositions containing the compounds of formula (I). Due to the odorant properties thereof, the compounds are highly useful in perfumery, especially for cosmetic products and household products.

摘要:(−) 3a,6,6,9a-tetramethylperhydronaphtho[2,1-b]furan (ambrox) is a strong aromatic compound used widely in a variety of perfumery applications and is highly prized for its musky odor. We report novel polar metabolites of (−)3a,6,6,9a-tetramethylperhydronaphtho[2,1-b]furan prepared by a novel process of microbial fermentation using a fungi, Fusarium lini , of unique structures that would be difficult to predict opening up the possibilities of their chemical synthesis. The polar metabolites discovered have stronger aromatic characteristics and offer a new highly prized odiferous characteristic quite different from that of the parent compound and thus can be used in the preparation of perfumes, odor-masking and other odor-management applications.

摘要:Our invention relates to catalysts and their use in the synthesis and conversion of alpha-olefin-containing products, essentially alpha-olefins, primarily from paraffins of renewable origin, having a carbon number of 11-45, and mixtures thereof, which mixtures contain paraffins having a carbon number of 11-45. The main steps of the process are the heterogeneous catalytic dehydrogenation of paraffin with a new zeolite-supported catalyst based on Pt, Pd or Ni, and then the conversion of the resulting olefin-containing product mixture, containing mainly straight-chain internal monoolefins, to lower homologous alpha-olefins—namely, the homogeneous or heterogeneous catalytic ethenolysis by using a ruthenium complex metathesis catalyst (i.e., metathesis using excess ethylene or ethylene metathesis), and/or tandem isomerization and metathesis reactions by using homogeneous or heterogenized homogeneous ruthenium complex metathesis catalyst in combination with a homogeneous or heterogeneous olefin isomerization catalyst (i.e., isomerization metathesis, hereinafter referred to as ISOMET), and/or tandem isomerization and ethylene metathesis by using a homogeneous or heterogenized homogeneous ruthenium complex metathesis catalyst in combination with homogeneous or heterogeneous olefin isomerization catalyst (i.e., isomerization ethylene metathesis, hereinafter referred to as ethylene ISOMET).
