摘要： A solid catalyst, such as a molecular sieve catalyst or solid acid catalyst, is supported by a binder, such as amorphous silica or alumina, wherein the binder is charged with metal ions to form an ion-modified binder. The ion-modified binder is capable of attachment to polar contaminants and inhibit their contact with the catalyst. The catalyst can be a zeolite and can be the catalyst for an alkylation reaction, such as the alkylation of benzene with ethylene.

摘要： Alkenylaromatics are produced by catalytic oxidative dehydrogenation of alkylaromatics employing a redox catalyst which is bismuth oxide, in combination with an additive compound of an alkali metal and/or an alkaline earth metal, on a titanium diooxide carrier. In a first reaction step, an alkylaromatic starting material is oxidatively dehydrogenated with the redox catalyst in the absence of molecular oxygen with attending reduction of the redox catalyst. In a second reaction step, the reduced redox catalyst is reoxidized with an oxygen-containing gas.

摘要： A process for producing a monoalkenyl aromatic hydrocarbon which comprises alkenylating a side chain of an aromatic hydrocarbon compound having at least one hydrogen atom at the .alpha.-position of a side chain (such as o-xylene) with a conjugated diene having 4 or 5 carbon atoms in the presence of a catalyst slurry prepared by adding an aromatic hydrocarbon compound to a catalyst comprising a alkali metal and an alkali metal compound. In the aforementioned process, it is particularly effective that the catalyst slurry is prepared by adding the aromatic hydrocarbon compound after the aromatic hydrocarbon compound has been deoxygenated and dehydrated by distillation, and the catalyst slurry thus prepared is supplied to the reaction system. According to the aforementioned process, an industrially useful monoalkenyl aromatic hydrocarbon compound, such as a monoalkenylbenzene, can be produced at a high selectivity, in a high yield, and with enhanced safety and stability for a long time.

摘要： There is disclosed a linear block copolymer comprising at least one triblock I--B--I, wherein I is a block of at least one polymerized conjugated diene of at least five (5) carbon atoms, such as isoprene, and B is a block of a polymer of at least one conjugated diene, different from that used to polymerize the block I, of at least four (4) carbon atoms, such as 1,3-butadiene. The B block is selectively hydrogenated, while each of the I blocks is unhydrogenated and therefore retains a sufficient amount of its original unsaturation to vulcanize the copolymer. There is also disclosed an alternative linear block copolymer containing at least one triblock of the first polymer block made from a minor proportion of at least one aryl-substituted olefin, such as styrene, and a major proportion of at least one conjugated diene used to polymerize the block I, the second middle polymer block of at least one diene used to polymerize the block B, and the third polymer block which is the same as the first polymer block. In this alternative copolymer, the middle block is also selectively hydrogenated, thereby leaving the terminal polymer blocks with a sufficient amount of their original unsaturation to vulcanize the copolymer. The polymers can be crosslinked or functionalized through the terminal blocks containing the vinyl unsaturation. There are also disclosed random linear and star-branched block and random copolymers made from the same monomers as the linear block copolymers. Also disclosed are methods of producing the polymers and selectively hydrogenating the aforementioned polymerized dienes.
