The invention relates to a method for preparing a cosmetic composition comprising the preparation of isododecane of natural origin and the mixture of isododecane formed with at least one compound selected from among: waxes, oils, film-forming agents, dyes and mixtures thereof. The invention also relates to the resulting cosmetic composition.

Methods of producing substituted and non-substituted beta-methyl styrene by a cross-coupling reaction are provided. The disclosure also provides for methods of preparing (E)-Anethol and related compounds by a cross coupling reaction of potassium allyltrifluoroborate and 4-bromoanisole and aryl halides. Compounds, compositions, and methods of treating disorders utilizing beta-methyl styrene are also provided.

Increase propane dehydrogenation activity of a partially deactivated dehydrogenation catalyst by heating the partially deactivated catalyst to a temperature of at least 660° C., conditioning the heated catalyst in an oxygen-containing atmosphere and, optionally, stripping molecular oxygen from the conditioned catalyst.

Methods and apparatuses are provided for producing hydrocarbons. A method for producing hydrocarbons may include two or more reactors having a distributed aromatic rich feed and hydrogen system. Using this configuration, the aromatic rich feed and hydrogen streams are split equally to all reactors wherein each reactor contains a catalyst. The outlet from the last reactor may include a recycle that may be injected into the inlet of the first reactor.

Zeolites having highly dispersed bimetallic clusters, uniformly distributed in size and composition, encapsulated therein are disclosed. Metal encapsulation and alloying is conferred by introducing ligated metal cation precursors into zeolite synthesis gels, which are subsequently crystallized hydrothermally to form zeolites with metal cations occluded in the pores. The ligated cations are anchored to the zeolite framework via siloxane bridges which enforces their uniform dispersion throughout the zeolite crystals. Treatment of the crystallized zeolites in O.sub.2 and then H.sub.2 forms bimetallic clusters, which remain narrowly distributed in size and composition.

A process for isomerizing an aromatic cut containing at least one aromatic compound containing eight carbon atoms per molecule is described, comprising bringing said cut into contact with at least one catalyst comprising at least one metal from group VIII of the periodic classification of the elements, at least one zeolitic support comprising a zeolite selected from zeolites with structure type EUO and MOR, used alone or as a mixture, and at least one matrix, such that the specific surface area of the matrix in the zeolitic support of said catalyst is in the range 5 to 200 m.sup.2/g.

The invention relates to a novel process for the preparation of 2,2′-bis indenyl biphenyl ligands of following formula (3): The invention also relates to metallocene complexes prepared using the novel process for the preparation of 2,2-bis indenyl biphenyl ligands.

Methods of producing gold-palladium catalysts suitable for use in the production of vinyl acetate may include drying the catalyst after the incorporation of a promoter at higher temperatures (e.g., 160° C. or greater) to restructure the metals and/or alloys on the catalyst. The restructured catalyst advantageously has increased catalytic activity and improved stability.
