    摘要: The present disclosure provides a series of new and improved porous polyamide aerogels derived from multifunctional aromatics that combine the high mechanical strength of aramids with the pore structure of aerogels. The polyamide aerogels have a hyperbranched structure, relatively low density, high porosity and may be derived from functionalized monomers having more aromatic groups than functional groups. The present disclosure also provides a new method for producing the porous polyamide aerogels by polymerizing an aromatic multifunctional carboxylic acid or a ferrocene multifunctional carboxylic acid with a polyfunctional aromatic isocyanate at moderate reaction conditions followed by drying with liquid CO2. Also disclosed are various methods of use of these polyamide aerogels in a variety of applications.

    摘要: A process for the synthesis of a monounsaturated nitrile-ester (acid) by cross metathesis starting from an unsaturated compound I including at least one trivalent nitrile, acid or ester functional group, wherein the process includes a stage in which two types of cross metathesis are alternated consecutively: — a first type of cross metathesis cm1 with an acrylic compound II chosen from acrylonitrile, acrylic acid or an acrylic ester, one of the compounds I or II including a nitrile functional group and the other of these compounds II or I including an acid or ester functional group, and—a second type of cross metathesis cm2 with a light C2 to C4 alkene compound III. Also, a process for the synthesis of an α,ω-amino ester (acid) obtained by a process including a stage in which the two types of cross metathesis defined above are alternated consecutively, followed by a hydrogenation stage.

    摘要: A method is described for the preparation of 1-octene starting from butadiene, wherein in a first step (a) the bis-hydrodimerization of butadiene to 1,7-octadiene is effected in the presence of a catalyst based on palladium containing one or more tri-substituted monodentate phosphines, in an aprotic polar solvent, in a second step (b) the partial catalytic hydrogenation of 1,7-octadiene to 1-octene is effected in the presence of a titanium compound activated with one or more metal alkyls of group 13 (selected from boron, aluminum, gallium, indium).
